Found this colour matching guide online, do you agree or is it questionable?

It's not wrong, but I don't know how helpful it is. I think it could be helpful for identifying complimentary colors, but it's missing some context about which articles of clothing are which colors.

For example, it lists pink as a matching color for light blue. IMO, light blue pants with a pink shirt works fine, but a light blue shirt wouldn't work so well with pink pants. In general you'd want your pants a darker color or cooler tone than your shirt.

(I usually stick to blue - white - brown, so really not an expert on colours)

These color combos look fine in general, I think it’s a good rule of thumb.

Can't get past the comma splice.

Total and absoute pedantry. Complementary.

This is the first thing in awhile I've not seen load for me. I use Voyager. What apps are you guys using tk see whatever this graphic is?

EDIT: Seems to work for me now! Weird... Cool chart. It seems like it could be useful.

Purple and orange seems pretty questionable, but the rest looks reasonable.

Most of these look good, green+orange and purple+orange and purple+green are all really rough without a lot of care though
