Does your screen show the right colours?
Tubomix computes colours like real paint, but your screen is what shows them. A screen that is too dark, a night filter or a “warm” setting change what you see. Three small tests, one minute.
1. The ten values
From black (1) to white (10), every square should stand apart from its neighbours.
Near black: you should see five squares.
Near white: you should see five squares.
Dark squares run together? Turn the brightness up. Light squares run together? Turn it down a little.
2. The neutral grey
This square is a perfectly neutral grey. If it looks yellow, orange or bluish, your screen has a setting that tints everything: “Night Shift” or “True Tone” (Apple), “Night light” (Windows), “Eye comfort” or “Blue light filter” (Android). Turn it off while you mix.
3. Vivid colours
The strip should flow smoothly through every colour, with no sudden step and no washed-out patch.
Advice
- Mix and compare under the same light as your painting, daylight if you can.
- Keep coloured lamps and direct sunlight off the screen.
- No two screens show exactly the same colour. Tubomix gets you close; the last touch is always made on the palette, with your eyes.
- A photo of an object depends on the light and on the phone: take the colour you pick as a starting point, not as the truth.
Why no dark mode?
A colour does not look the same on black and on a light background: on black it looks lighter and brighter. A mix that looks right in a dark mode would look wrong on your canvas. So Tubomix always keeps the same neutral grey around colours, like the grey palette many painters use. That is also why the app ignores your phone’s dark mode.
