I’m color blind myself and the app doesn’t bother me. I saw that post as well and didn’t understand why that would be a reason not to want to use TR. I’m more of a numbers person any way so that is all I focus on.
Whilst I have no problem with the red/green bar on TR, as someone who is red green colourblind I always appreciate efforts from devs to make games/software more accessible to those who are colourblind so this is a +1 from me.
I don’t think this would put anyone off TR at all - the other poster just wasn’t aware of the colour changing visual indicator on the bar.
Of course, you can see the power line, the raw numbers and the bar on the line as other indicators without the red=missing green=on target but it’s a relatively minor thing TR could do to increase their accessibility.
