Describe the Feature you'd like

Allow users to set colors for labels, fields and background. This is really needed for the color vision impaired.

Example: For the red-green vision impaired (deuteranomaly/deuteranopia), the red label in the widget appears nearly black and is unreadable in dark mode. The green label appears nearly white and the color meaning is lost.

At the very least, provide a b/w or grayscale setting (reversed for black mode).

Why do you want this feature?

To allow the color vision impaired to enjoy the full use of the app.

I am also color-blind (although to a small degree) and there are several instances in this app when i was set back by how the colors were used.

Here some other examples:

• In the graphs talked about in issue #198 , the colors can be misleading as the gradient for WLAN usage gets pretty close to the main color of the gradient for Mobile data usage.
• The icons in the parameters are all in a different color. See: Although arguably pretty, it creates a difference in contrast between each of them, which makes them appear as valued differently, the brightest being the most important. Also creates visual noise, something you'd probably not want in the parameters of a monitoring app, pretty serious topic.

I'll also add that, as a coulor-blind, i much prefer apps that use Material Design 1 or Material Design 2 as a standard, because the information is usually much more clearly presented.
