Anyone have experience with this? Is Rit Dye even still sold in stores? I have one sort of decent pair of Columbia shorts that I love. They have a small tear that I can mend, but the brown color has faded in spots, due to sweat while hiking, I believe. After letting my hair go gray, I've been transitioning my clothes as I get anything new to mostly a palette that matches gray, with a few black items (not a fan of black usually, due to cat hair in my household). However, I think black would be good for these shorts possibly. And then they'd go with a lot and hopefully last at least a few more months. Any input, suggestions?
