I usually buy last seasons clothes, and feel the same way when the only clothing piece left is an EXTRA SMALL, or neon green color. However, I did just buy some discounted Patagonia (I also got the Houdini in dark blue) and picked up the nanopuff in a bright teal color (Patagonia calls it Grecian Blue.)
When I look through my camping clothes, I see tons of black and dark green. I used to prefer those colors, and am still comfortable in them. However, I do not backpack alone, and when I am with others, I enjoy seeing their varied colors of clothing. It has become fun to me, and I do not mind seeing people off in the distance with rainbow colored clothes. So, I am definitely a color convert. Patagonia's bright blue jacket is the start of something great for me! hehe.
Clay, you can send me a PM when you are visiting the Sierras. I'll try to wear only earth tones for you. :)
