Fix #3

Thanks for the PR! Though, I now regret making the diff colors the bright versions of the palette. I do not think it looks good.

(Red and green is bright and yellow is base, since yellow generally seems brighter in this palette)

Or just reverse to use without background color whichever you prefer. This way a bit harder to see change and text change

Yes, I have tried using the dim version here, and white~ delete fg

[AlexvZyl]

Dim looks better, but I think specific colors should be added for the diff.

[AlexvZyl]

This is fine for now, at least it is readable. I will add colors specifically designed for diff in the morning.

Thank you!
