acceptance tick box for ajax fields isn't visually clear

[Robert Collins]

The 'tick' box shown when editing a field (like the bug summary field)
isn't clearly a tick, at least to me (red-green colour insensitive).

It appeared to be a featureless grey circle.

[Martin Albisetti (beuno)]

Interesting. I converted it to black and white, and it still looks like a tick to me, even more so next to the "X" besides it.
What do you think we could do to improve it?

[Matthew Paul Thomas (mpt)]

Grey-scale conversion is not an accurate simulation of any form of color insensitivity, short of total color blindness. <http://vischeck.com/examples/>

A simple fix would be to make the green substantially darker.

(BTW, Incomplete is for when the *problem* is insufficiently described. Any suggested solution is a bonus!)

Going to black and white isn't a good way to test how it degrades.

Try running daltonize on it:
