Hello love this app dearly

Hi. I am new to this entire app still. I'm currently adding my small GBC console collection. I'm only finding three choices for colors. I added a pic of my GBC's. I don't see any color choices for quite a few? The green, pink, purple variants ect.  That's the only thing I've come across I feel like maybe could be changed?  Only if other people think it's a good idea though.  I realize a lot of the colors are only a couple of dollars off.  I still think it'd matter to serious collector's being able to add each GBC and its color variants.
