Although it is now somewhat easier to tell the ores apart (for me, too and I am not colorblind), I still see how it can be sometimes hard to distinguish. I've said this in other threads, too but for issues like these some checkboxes for game customization would be fine. In this case may be something like different pics for ores plus an easy to see letter inside in order. For liquids some sliders to change colors. Although I am not sure if liquids use some sort of pics and the color is so to speak hardcoded. Something that should be easy to change is the cursor. That thing and I are not on friendly grounds. On grounds SO not friendly I had to take action and get myself a mod to make the thing more visible so my guy doesn't get eaten because I couldn't find the cursor in time to avoid harm.
