There are test strips for brake fluid though I've only gotten them from BG.
Brake fluid absorbs moisture and darkens as it does. too much moisture and the fluid can boil or corrode the brake lines, calipers etc...
If it is dark It is not a bad idea to flush or bleed the brakes. start at the right rear then the left rear then the right front then the left front.
