I looked a bit at the usability guidelines and wrote the attached
elisp file for testing new colors. There is an interactive function
that displays the new fonts and contrast ratios.

Testing your suggested colors I found that the contrast ratio is very
good. But it does not seem necessary to make the contrast ratio that
large as you have done. The usability guidelines suggests that a ratio
of 4.5 is enough. So there is room for colors that are more
distinguishable.
