Dark Blue Navigation Buttons

[michael smith]

Some Open Office command buttons (for instance in the Find/Change tool) are
so dark blue (at least on a mac) that they are nearly unreadable. I've
followed suggestions on the Community Site and also from Googling but none
of it works. Why was such a terrible color contrast chosen and is there any
way I improve it? I'm elderly and eyesight is not good so it's additionally
frustrating. Thank you in advance for any help you can give.
