White background

[Piotr]

I’m used to work at white background. I believe you see more (like drawing at white or black paper).
I have switched background to white. Coursor switched automatically from white to black - OK. But how to switch Measurement distance tool to be black?
Edit:
Or may be coursor is always gray - is to thin to be sure.
Edit2:
When I tried to draw lines (I’m in footprint editor) coursor disapeared

I noticed that thin lines are much more visible when the background is dark and the lights are light. Especially if the thin line must go over other things of medium lightness. This is quite noticeable with ratsnest lines. I fear to implement a light theme we would need to be able to change the line thickness for things like ratsnest, cursor, …

The colours I have used till now were defined by my brother 20 years ago. Since I took PCB designing in about 2004 I never thought about colours. They just were as they were. But habit is the second human nature so I thought about working in KiCad in ‘my’ colours.
Here is the example how I’m used to see PCB.
First - my old PCB after Unroute-All:

And the same fragment routed (zones not shown):

I didn’t noticed any problems with seeing ratsnest lines (I use red for VCC and blue for GND connection).
My first feeling when I sow PCB in KiCad default colours was that everything is too dark. For example KiCad’s Red is (RGB) 132,0,0 what for me is rather brown not red. Also green (0,132,0) is rather dirty green.
I think that if I can’t set the coursor colour than it should be set automatically to be visible if I change background to white. I will report it as a bug. May be developers agree with me and change how the coursor color is defined.
