Colour screen

Any solid colour, fullscreen, in two taps.

Twelve presets and every HEX value in between — with brightness and colour-temperature controls that recompute the real colour of the panel.

How to use it

Three steps, no learning curve.

  1. 01

    Pick a colour

    Tap one of the twelve presets, or type any HEX value. The fullscreen stage updates immediately — no page reload.

  2. 02

    Tune brightness and warmth

    Dim the colour for dark rooms, or shift it warm or cool to match the light around you. Both controls recompute the real hex value.

  3. 03

    Copy or export it

    Copy the exact hex and RGB values for your design file, or export the colour as an image at up to 8K resolution.

Field notes

Why brightness and warmth change the hex value.

Most colour tools apply a translucent overlay to “dim” a screen, which quietly changes the colour. We do the maths instead: brightness scales the RGB channels and warmth blends the result toward a warm or cool reference white, so the value you copy is the value on screen.

Matched fill light

Set an exact brand colour and hold a phone next to a product for consistent, repeatable lighting on set.

Chromakey checks

Fill a screen with key green or blue to check how a camera, app or codec handles the edge of a key.

Mood and ambience

A phone propped against a wall becomes a soft coloured light for a room, a shelf or a video call.

FAQ

Common questions

What is this colour suite for?

Turning any screen into a precise, single-colour light source: matched fill light for photography, green screen alternatives, chroma checks, mood lighting, product backgrounds, and colour reference on set.

Does the brightness slider change the hex value?

Yes, and that is deliberate. Dimming multiplies the RGB channels, so the value you read and copy is exactly the colour the display is showing.

What does the warmth control do?

It blends the base colour toward a warm 3200K tone or a cool 6500K tone while keeping a flat, solid field. Useful when a saturated colour is too harsh at night.

Can I get exact sRGB values for design work?

The readout shows the exact sRGB hex and RGB triplet being painted. Keep brightness at 100% and warmth at neutral to export the untouched colour.

One tap and the screen is yours.
