Hello,

The *Colors* buffer has black text on color backgrounds that is not always readable.

Line 1 has black text on black background. The cursor does blink the character which is then readable, very, very briefly.

Line 22 has black text on blue background which for me isn’t easy to read. The medium blue on the next line is difficult for black text.

I’d like to suggest color contrast arcs through a distorted triangle colorspace for choosing textcolor always in contrast to the background color for easy reading. In the case of black, blue, medium blue background the text color is white. Perhaps, only a dozen special cases are needed to switch black to white text color and the colorspace idea is overkill.

Thanks.
