Hi,
the current color temperature steps in the display settings do not reflect how color temperature is perceived by humans.
At present, the selectable values are about these:
6000, 5900, 5800, 5700, 5550, 5400, 5000, 4500, 3900, 3300, 2350
Because perception is not linear in Kelvin, changes at warmer temperatures (lower values) appear much larger than the same numerical changes at cooler temperatures. This makes the higher, cooler range (around 6000-5400 K) nearly indistinguishable, while the jump from 3300 K to 2350 K feels excessive.
To improve this, I would suggest:
1. Use a perceptually linear scale (Mireds):
Mapping the range evenly in Mireds would produce more consistent perceived steps, for example (converted to the Kelvin scale):
6000, 5193, 4578, 4093, 3701, 3377, 3106, 2875, 2676, 2502, 2350
2. Allow continuous adjustment:
Instead of fixed steps, a continuous control would let users select their preferred exact value.
Either change would significantly improve usability.
Thanks for considering this.
