1x1 UTM squares hard to distinguish

[SanderDevisscher]

Is your feature request related to a problem? Please describe.
Currently the 1x1km squares on the species information observations map are green.
Especially when you activate the globe these are very hard to distinguish.

Describe the solution you'd like
I would like to see them in another color with contrasts enough from the background map. I would say red but this gives issues for our color impaired users. suggestions are welcome.

Current version (Lithobates catesbeianus):

It's currently based on the order in the inbo_palette()

(1) I can exclude the first two (green and blue) colors for this plot, so it starts with 'orange'.

(2) I can exclude the first four colors, so it starts with dark purple

(3) I can hard-code red squares

@SanderDevisscher preference?

[SanderDevisscher]

@ThomasScheppers @Fhuysent can I borrow your colorblindness ? can you please give your preference ?

[Fhuysent]

Given the choice between those three, I prefer the red (option 3).
Purple is also OK, but not very nice I think. Orange is difficult to see for colorblinds.

[SanderDevisscher]

personally I would go for red also

[mvarewyck]

Is it fine to add red as the first color for the other plots too relying on this piece of code?

[SanderDevisscher]

@Fhuysent what do you think ?

[Fhuysent]

Yes, looks great! Red and green can be somewhat tricky to use next to each other, but these are different enough for even colorblinds.

@mvarewyck go ahead

@Fhuysent Is the blue color also a good option?
