I just had my color profile done at the mall. They say that I am an Autumn, and I should accessorize with brown and beige. I can't seem to find any brown discs, so I will have to get a custom dye to match my bag!
Super bright (dayglow) pink actually would work for all seasons......contrasts heavily against white.....stands out in the green of spring/summer.....offers the a good contrast from the fallen leaves of fall for the most part.
What about blue? I think blue is the best color in all seasons.
I think that if you throw a pink disc in a pile of red and orange leaves you have a very low chance to find it.\
Either blue, or bright neon green for the fall. You gotta go opposite colors.
