About Custom Color

Sometimes you need an exact color and the preset list does not cut it. The custom-color page accepts any HEX value, a color picker, a brightness slider, and a warm/cool temperature overlay. Paste a HEX from your brand guide and you have an on-call lighting panel.

Brand Color Matching and Corporate Lighting

Paste your company's HEX color code into the input field and the entire screen fills with your exact brand color. Marketing teams use this during photo shoots to match on-screen backgrounds to brand guidelines, event planners project brand colors on lobby displays and stage screens, and interior designers test paint colors by displaying them fullscreen on a monitor placed against a wall. The brightness slider lets you evaluate how the color reads at different intensities, and the temperature overlay adds warm or cool bias to simulate different lighting conditions. Designers save the configured color as a PNG for mood boards and client presentations.

Streaming and Video Call Custom Backdrops

Streamers and remote professionals use custom color screens as branded backdrops behind their webcam or streaming camera. Enter any HEX value to match your channel's color scheme, team colors, or event branding. Content creators use different custom colors for different show segments, creating visual variety without changing physical sets. Podcast video feeds use custom color backgrounds to maintain a consistent visual identity across episodes. The fullscreen mode ensures no browser chrome or desktop elements are visible behind you on camera.

Photography and Product Shoot Color Fill

Photographers use custom color screens as seamless backgrounds for product photography, flat lays, and macro shots. Dial in any color to complement the product being photographed, then adjust brightness to control shadow density. The temperature slider adds warmth or coolness to match the shoot's creative direction. Food photographers, fashion stylists, and e-commerce sellers use this technique to create consistent, on-brand product images without purchasing multiple rolls of backdrop paper. Download the configured color as a PNG to use as a reference swatch during post-production color correction.

Interior Design and Paint Color Preview

Before committing to a paint color, display it fullscreen on a laptop or tablet and hold the device against the wall you plan to paint. The large color surface gives a far more accurate preview than a small paint chip or phone screen. Interior designers use this technique during client consultations to evaluate color choices in the actual room's lighting conditions. Adjust the brightness to simulate how the color reads in natural daylight versus evening lamp light. The temperature overlay helps preview the effect of warm versus cool light bulbs on the finished wall.

How to use it

  1. 01

    Pick any color you want

    Type a 6-digit HEX into the input, or click the swatch to open the native color picker. The 15-square Quick Palette below the inputs gives you ready presets, and keyboard 1-9 cycles through the first nine.

  2. 02

    Tune brightness and color temperature

    Open the controls panel (gear icon or press C). The Brightness slider dims the surface from 20% to 100% — useful for night work or for matching ambient room light. Keyboard + and − nudge it 5% at a time. The Temperature slider warms the screen toward amber (positive values) or cools it toward blue (negative), letting you bias a fixed hue without leaving the page.

  3. 03

    Go fullscreen

    Press F. The full panel fills the chosen color.

  4. 04

    Download the current view as a PNG

    Click the download icon in the top-right toolbar — it sits between the settings gear and the fullscreen button. We detect your display's physical pixel count (screen resolution × device pixel ratio) and rasterize the current configuration into a Retina-sharp PNG. The file lands in your browser's default downloads folder; to save straight to the Desktop, enable 'Ask where to save each file' in your browser settings. The filename includes the resolution so you can keep multiple variants side by side.

Frequently asked

The shortest path between you and the answer.

Can I export the exact color I dialed in?

Yes. The download button in the top toolbar saves a PNG of the current HEX + brightness + temperature combo. The filename encodes those parameters so you can keep multiple revisions.

Is this tool free?

Yes. Every ScreenTools.co tool is free, with no account, no paywall, and no install.

Does it work on mobile?

Yes. Layouts adapt to phone and tablet screens. Mobile Safari restricts true fullscreen, but the page fills the viewport and you can add the page to your Home Screen for an app-like experience.

Does it work offline?

Once a tool's page has loaded once, the runtime is local. A few tools that fetch fonts or icons need the first hit online; after that, refresh works offline.

Does this collect my data?

No personal data leaves your browser. The site has lightweight, privacy-respecting analytics for aggregate counts (which tool was opened) and nothing else.
