Colorblind-friendly optimization progress

Is your feature request related to a problem? Please describe.
I really like the new Optimizations tab and I found it immediately useful to assess currently running optimization progress. That being said, I am having trouble understanding or at least estimating the remaining percentage of work. There is no numerical estimation of the progress anywhere and the only way to assess is to look at the segment colors.

The current UI shows segments with green, yellow and gray indicators, and these are really bad colors for me to distinguish with these small square icons as I have red-green color blindness. If there could be a high contrast mode for the UI, I would greatly appreciate it.

I really can't tell how many squares are gray in the bottom example.

Describe the solution you'd like
A numerical estimation of the progress (e.g. 10/40 segments finished) and a colorblind mode for the UI that replaces greens with orange and yellows with blue (similar to what Wordle does for example, see below).

hey @kaancfidan , i've implemented the changes so the high-contrast palette applies consistently across the progress grid, timeline chart, and optimization tree. Btw thanks for the detailed write-up - the Wordle comparison was really helpful for nailing down the right palette.

Let me know if the color choices work well for you and i would be glad to tweak if needed!
