So, the Spooky Mounts came with four dye channels, making it possible to dye them in a way that a person basically has colorful base mount, save the spooky smoke effect. Granted, I don't have these skins, and I don't plan to buy a whole bundle.
However, I think it would be awesome if we could dye the mount skins in the Mount Tab to see what they can look like with our own combination of dyes before we buy them. I think the gliders' preview already does this with dyeable gliders--they show what the glider would look like with your current glider's dyes. However, since the base mounts have only channel, there's no real way to make it work with skins that have 4 channels.
(Note: I'm still fully behind being able to buy one additional channel for the base mounts as shown here)
If we had a way to preview how our dyes would look on the skins we had not purchased, it would help those of us who are on the fence about getting them decide whether or not the skins would work out in the end.
Thank you for taking the time to read.
