The Wise Boiled Potato

I decided to breach the design instructions regarding active states of radio buttons. The design suggests that a checked radio button would acquire a light gray background, whereas a hovered-over one would get an orange background. This is in my opinion pretty misleading.

Normally, people associate a change of color with a change of state, and a big change of color with a samely big change of state. If a radio button was gray then turned orange, a user might suggest it has got checked! So, I flipped colors. A checked radio is orange, and a hovered-over one is light gray.

What do you think about this? Well done? Na-ah?
