Since the DX11 update release, the graph for the gear ratio is blue colour which I find hard to see on a Black background. Any way I can change that?
I believe you can DL other UI mods. You may find their contrast more to your liking. https://forum.studio-397.com/index.php?threads/ui-black-edition-by-team-gsv-1-0.50368/ http://www.racedepartment.com/downloads/black-carbon-ui.3461/ those are two examples.
Those links appear to be for UI's for earlier versions. I don't want to change the current default UI, just the colour of that graph. Must be other users are finding it difficult to see.
You can unpack the UI, modify the .OSC file that defines the UI layout and colours, and repack it as a UI .rfcmp which you can then install and use. I'm not 100% sure that graph colour is able to be modified (haven't checked it specifically) but I'd give it a better than 50/50 chance.
