I acknowledge that I'm getting older, and so are my eyes, but ...
The default colours for quotes is also difficult for me to read
(i.e. black text on a brown background?)
I'm in favour of something easier on the eyes, with reasonable contrast
(e.g. arbitrarily, perhaps the colours in the "Quote button"? Pale/eggshell background ... ?)
Right now I'm typing in a pale green box, with black text - I'm thinking a slightly paler, yellow quote box would be okay on the eyes ... (but, I can't remember what they taught me about colour blindness, except for red/blue/green or something like that ...)
Any medics in the house?
