@Suty Ok but why is it possible to change for Rain/thunder and not Weather Radar?

i need some help. i'm trying to change some colors for the "weather radar," and while most colors update correctly, the one for 0 mm/h (default gray) doesn't change when i try to modify it.

it works fine in the rain/thunder mode but not for the radar itself. is this a glitch?

example, here i changed the color for rain/thunder (0mm) and it worked as expected, i apply some green:

but when i do the same for weather radar, it doesnt change anything:

i tried to tweak the 0.1mm/h values too and different ones but it seems that it doesnt really work
