About 83K Screen Colors
Every screen you own emits light. 83K gives you precise control over exactly what color that light becomes.
83K Screen Colors (83k.net) is a free, browser-based tool that transforms any display into a controllable color panel. Open the page, choose a color, and your entire screen becomes a uniform field of light at exactly the hue, saturation, and brightness you selected. The 83K interface fades away automatically, leaving a clean, distraction-free expanse of color filling your display from edge to edge. Your screen becomes a photography backdrop, a video lighting panel, a green screen stage, an ambient light source, or a color reference surface, depending entirely on what you need in the moment.
How 83K Works
83K operates entirely within your web browser. The moment 83k.net loads, a complete screen color control toolkit appears on screen. You select a color through any of several input methods, your screen fills with that exact color instantly, and 83K's interface fades out of view.
The auto-hiding interface is the design decision that makes 83K work as a genuine production tool. After a configurable period of inactivity, typically five seconds, every control element, every button, and every panel disappears. The countdown progress bar vanishes. The scrollbar hides. Your screen presents absolutely nothing except the chosen color. When you need the controls back, a mouse click, a touch, a mouse movement, or a press of the Escape key brings 83K's full interface into view immediately.
You configure the exact trigger that reveals the hidden interface, you set the timing before the interface fades, and you choose whether a small reminder hint appears during the hidden state. A pin button locks the interface in place permanently when you want continuous access to the controls. These configuration options live in 83K's settings panel below the main color display area.
Solid Colors
83K offers multiple paths to selecting a solid screen color. The circular color picker provides direct visual selection across the full color spectrum. The hex input field accepts any six-character hexadecimal color code and recognizes common color names like "red", "teal", "coral", and "greenscreen" as typed words. A row of quick-access swatches provides one-click selection of black, white, red, green, blue, yellow, cyan, magenta, orange, and gray.
The moment you select any color, 83K fills the entire viewport with that color, updates the favicon to match, adjusts all interface elements for optimal contrast against the current background, and stores the selection in your browser's local storage so your chosen color persists across sessions.
Kelvin Color Temperature Presets
Photographers and cinematographers describe light color in Kelvin, a temperature scale that maps directly to the warm-to-cool spectrum of natural and artificial light. 83K provides six Kelvin presets that correspond to real-world photographic lighting conditions:
- 2000 K produces a deep amber glow corresponding to candlelight and the warm end of tungsten lighting, useful as a warm fill light for portraiture and product photography with warm-toned subjects.
- 3000 K matches the warm white of halogen lamps and classic incandescent studio lighting, producing the soft warmth familiar in residential and studio environments.
- 4000 K corresponds to neutral white fluorescent lighting, producing a balanced tone between warm and cool that serves as a clean, even reference light.
- 5000 K replicates midday sunlight, the standard daylight reference point used in color-critical work, display calibration, and print proofing environments.
- 6000 K corresponds to overcast daylight and north-facing window light, producing the cool, slightly blue-white tone that photographers associate with soft, diffused natural illumination.
Two additional presets serve chroma key production workflows. The green screen preset outputs the standard chroma key green at #00B140, and the chroma blue preset outputs the standard compositing blue at #0047AB. Both values match industry-standard chroma key colors used in film, broadcast, and visual effects production.
The "K" in 83K's name references Kelvin, positioning the tool within the language of professional color science that photographers and cinematographers use daily.
Color Gradients
83K's gradient editor creates smooth color transitions across your entire screen. Two color pickers define the start and end colors. A slider sets the rotation angle from 0 to 360 degrees. Three gradient types are available: linear gradients that flow in a straight line, radial gradients that expand outward from the center, and conic gradients that sweep in a circle like the face of a clock.
Ten gradient presets provide ready-made combinations, including Vaporwave, Sunset, Ocean, Mint, Cosmic, and Midnight, each selectable with a single click. The gradient CSS output displays in real time and copies to your clipboard on click, giving web developers and designers immediate access to the exact CSS code producing the current screen gradient.
Light Effects
83K's effects engine transforms your screen into a dynamic light source. Fourteen light effects produce real-time animated color patterns directly on your display:
- Strobe alternates between white and black at high frequency, producing a rapid flash effect for stage and event lighting simulation.
- Slow Strobe alternates between white and black at a measured pace suitable for signaling and attention-drawing applications.
- Red / Green and Red / Blue alternate between their respective color pairs, useful for emergency lighting simulation and color-cycling visual effects.
- Rainbow cycles continuously through the full hue spectrum, producing a smooth, endlessly rotating color wheel across your entire display.
- Candlelight simulates the irregular warm flicker of a candle flame, varying orange and amber tones randomly to produce a convincing organic glow.
- Animated Gradient rotates a two-color gradient continuously, producing a slowly shifting color field that works as dynamic ambient lighting.
- Color Wave sweeps a single hue slowly across the color spectrum, producing a calm, hypnotic transition that fills the room with gradually changing light.
- Warm Pulse breathes gently between warm amber tones, producing a soothing, rhythmic glow suitable for relaxation environments and meditation spaces.
- Aurora shifts between two complementary hues while rotating the gradient angle, mimicking the slow, ethereal movement of northern lights across a night sky.
- Ocean transitions between deep blue and teal tones with a gradual angular drift, evoking the shifting colors of deep water under changing light.
- Photo Flash fires a brief burst of white light against a black background at irregular intervals, simulating a camera flash for test exposures and flash-timing practice.
- Breathing fades smoothly between black and white in a slow, rhythmic cycle, producing a calming pulse of light that rises and falls like a slow breath.
- Lightning delivers a sharp, instantaneous white flash against a black background at random intervals, simulating the unpredictable illumination pattern of an electrical storm.
Every effect previews in a dedicated panel before you apply the effect to your full screen. An optional auto-stop timer halts any running effect after a set duration and returns the screen to a fallback color of your choice, ensuring effects do not run indefinitely if you step away.
148 Named HTML Colors
83K displays a complete gallery of all 148 standard HTML and CSS named colors. Each color appears as a visual swatch card showing the color name, the CSS keyword, the hexadecimal code, the RGB values, and the recommended contrast color for text readability. Clicking any color card immediately sets your screen to that color and scrolls the page to the top for a clean, fullscreen view.
Color family filters let you browse by category: red, orange, yellow, brown, green, cyan, blue, purple, pink, white, gray, and black. Each named color has a dedicated, permanent URL, making every color page directly linkable and shareable. Every color name, description, and URL slug carries a full translation across all supported languages with appropriate URL-friendly romanization.
Export and Development Tools
83K provides two export paths. The PNG download button captures your current screen color or gradient as a full-resolution PNG image sized to your viewport dimensions at your device's native pixel ratio. A photographer working on a 4K display at 2x pixel ratio receives a PNG at full 4K resolution. The CSS copy button places the exact CSS declaration producing the current screen appearance onto your clipboard, ready to paste into a stylesheet, design tool, or development environment.
The settings panel displays real-time viewport dimensions, physical screen resolution, and device pixel ratio, giving developers and photographers immediate access to the display specifications they need for resolution-aware work.
Who Uses 83K
Portrait and product photographers use 83K to fill a secondary monitor or tablet screen with a specific color, creating a soft, even-toned backdrop or fill light panel positioned behind or beside the subject. The fullscreen display produces a clean, uniform light surface across the entire panel area.
Video producers and streamers use 83K as an on-set lighting panel, positioning a laptop or tablet screen running 83K to add directional color wash to a scene. The Kelvin presets provide immediate access to photographic-standard color temperatures, and the gradient mode enables two-tone lighting from a single screen.
Content creators producing green screen or chroma key footage use 83K's dedicated green screen and chroma blue presets, which output the exact standard chroma key colors used across professional compositing and visual effects pipelines.
E-commerce product photographers use 83K's solid white (#FFFFFF) or custom-colored screens as clean, uniform backdrops for small product shots. A tablet running 83K provides an evenly lit, edge-to-edge colored surface beneath or behind a product.
Web developers and front-end designers use 83K's named color gallery as a visual CSS color reference, with one-click access to every standard HTML color value. The CSS export function provides ready-to-use declarations for solid colors and gradients.
Interior designers and lighting consultants use 83K's Kelvin presets and custom color selection to preview how specific light colors interact with a physical space, materials, and furnishings before committing to a permanent lighting installation.
Stage and event lighting designers use 83K's light effects as prototyping tools, previewing dynamic color sequences and transitions on a screen before programming the same patterns into dedicated stage lighting hardware.
Display calibration professionals use 83K to fill a screen with known reference colors during monitor calibration sessions, verifying that the display's output matches expected values at specific hex codes and RGB coordinates.
