Cool White Screen

The same color as the White Screen

This page shows exactly the same color as the White Screen: #FFFFFF, with every red, green, and blue subpixel fully on. That is not a shortcut. "6500K daylight white" is the standard daylight white called D65, and D65 is the white point that the sRGB standard is built on. On a display that follows sRGB, the whitest white it can show already is 6500K daylight white, so there is no cooler or more accurate value to use.

We keep this page because many people look for a "cool white" or "daylight white" screen, and it is more useful to explain what they will get than to invent a different color.

Using it as a neutral light

1. 1

   Open it full screen. The browser toolbars around the color are gray and dim the light.

2. 2

   Turn off color filters. Night mode, True Tone, and blue-light filters warm the white, so it is no longer daylight white.

3. 3

   Place it close and adjust brightness. A screen is a small light source. For a video call, set it slightly above eye level and lower the brightness if the light feels harsh.

Limits

The match with 6500K holds only on a display set to sRGB with its standard white point. Some displays are set cooler or warmer, and then both this page and the White Screen show that display's own white. To get closer to daylight white, choose the display's sRGB mode or its 6500K color temperature setting, if it has one. The light comes from red, green, and blue subpixels, so it matches the color of daylight, not its full spectrum. For a warmer white, try the Warm White Screen.

This screen's exact value has its own #FFFFFF color page, with its RGB and HSL values and its contrast against black and white.
