Witness Makes Key Admission That He Never Saw Trayvon Martin Throw A Punch At Zimmerman

7. I want to know why since Zimmy was trained in MMA, he keeps assuming it was TM who was doing that

And I'd like to know how he could see the colors of the shirts when it was too dark out for an eye to be able to see color.

There are two types of photoreceptors in the human retina, rods and cones.

Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity.

Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones. There are 3 types of cones which we will refer to as the short-wavelength sensitive cones, the middle-wavelength sensitive cones and the long-wavelength sensitive cones or S-cone, M-cones, and L-cones for short.
