So remember that one post going around about how Hunk is probably colorblind. (I forget which specific type of color blindness it was) but basically everything was really dull. And you know how there are now glasses you can get that lets you see colors. I was think that Alteans or some other alien race would probably have something like that.
So when Allura and Coran find out that Hunk can’t see some colors they find him a pair of glasses or something like that that’ll let him see colors. And holy shit could you imagine how happy and emotional Hunk would be??? The lions are so brightly colored!!! How did he sometimes mix them up?? And wow Coran’s hair is really more orange than he realized. (They stop at a planet for a supply run and Hunk is just in awe of the grass and the sky and the trees it’s all so bright and defined and beautiful)
