It might suggest for example, that a beanie (if you wear a skull cap, designed like this might be more ideal than all white or all black. The black part is already blocked by the sun because it's under the solid part of a helmet shell, and can pull more heat off your forehead and back of you head, while the white part is reflecting sun thru the vents.
Your link seems to suggest that white clothing doesn't reflect heat back to your body any more or less than black. It doesn't actually say anything about heat conduction (as opposed to heat radiation) from your shirt directly touching your skin. I would be surprised if colour had any effect on heat conduction. But it's not something I've studied.
