I looked at an example of this on a chess talk page (last of the "what
links here" display) and could not see anything other than a
singly-coloured bar. I looked very close and then realized that it was
pale green to the left and pale red to the right - the worst combination
for me. After that, my brain could figure it out, since it knew what it
was looking at.
This should use more striking shades of red or green for such a narrow
bar or a wider bar so that the colour stands out more. A wide, black
line between the two parts of the bar to delimit the coloured regions
would help too.
