Wait if he's colorblind from birth, then how can he know what red looks like??

I’m pretty sure he gets to see colors as he experiences different emotions. For example he only saw red after the emperor betrayed him and he was angry so maybe red = angry. So maybe the past female lead helped him go through different emotions and made him see all the colors. Idk just my opinion. ヾ(❀╹◡╹)ノ~
