White — #FFFFFF
White screen.
Full white, #FFFFFF. The least comfortable colour to stare at, and the best one for finding dirt.
01 — Panel
The panel
Any hex works. Patterns are drawn in CSS, so nothing blurs when the panel goes fullscreen.

02 — Uses
What this colour is for
- Dust and fingerprints
- A white field turns every smudge into a shadow. Do this before you decide the panel is scratched.
- Paper white
- Hold the screen next to a sheet of paper. Paper runs warm or cool depending on the stock; most screens match neither.
- Cheap fill light
- A laptop at full white is a soft, slightly blue light source for small product shots. Ugly, works.
- Projector check
- White shows lamp uniformity and colour shift across the frame. Black shows the dust on the lens.
03 — Step by step
Testing a screen with it
Turn the lights down
Not off. You want to see the panel, not the reflection of a window.
Fullscreen at 100%
Half brightness hides every uneven patch you're looking for.
Compare with paper
Same light, side by side. Then decide whether you care about the difference.
04 — FAQ
FAQ
Is this #FFFFFF?
Yes. Pure white, all three channels at 255.
Why does it look yellow?
Night Shift, f.lux or a warm display profile is on. Switch it off before you judge anything.
Can I use it as a lightbox?
For tracing, roughly. A real lightbox is brighter and more even. For photos it's fine as fill.
