What I'd like to see for a dye system

One of the least popular parts of the current cash shop seems to be the dye system, being both RNG and consumable. Many people recommend using Guild Wars 2's dye system and I'd be very happy with it, but another game that does dying well I feel is Warframe.

The way Warframe does it is that it sells you color palletes that have a certain theme (e.g. Smoke- with shades of black and white, or Fire- with reds, yellows, and oranges.)

In Korea there is a subscription to get unlimited access to dyes for the month, so I feel that if they broke down the colors into categories and sold them as a one time purchase in similar sets, it could end up being a great dye system.

As a side note, having a deep dye system would help with the lack of costumes as well, because while 2 people may have the same costume, if they're dyed very differently, those 2 characters can look very different and unique

Edit Here is an example of the dye system in Korea: https://youtu.be/LJWhjju_Dz4
