Trait variations

[mdnssdesign]

Hi, is it possible to choose trait from list and then choose it's random variation while in DNA it still shows up as base trait?
for example:
-generator choose one trait from HAIR folder list:
-long#10
-medium#10
-mohawk#10
-assume that choosen trait is "medium", but "medium" can come in different colour variations like: red, blonde, dark etc...
so token metadata trait is "Hair: medium" (without color written down), but NFT image have that hair trait in random color.

I hope my question is clearly written :)
I tried to serch in discussions for that problem, but I might have missed it

Actually my knowledge about coding is close to zero but i foud an answer myself. I don't know it's best way, but it works. So if I want to have traits variations like color or something, but maintain the same trait value, I made new folder with name of trait value and in this folder I put every variation .png files. Each file have same name, just changed weight so explorer won't show error that files are the same names.

Eg.:
-HAIR <-- this is root/layer folder
---long#10.png
---medium#10 <-- this is the nested folder
---medium#20.png <---this is let's say blonde color variation
---medium#21.png <---this is brown color variation
---medium#22.png <---this is dark color variation
---mohawk#10.png

So now my Hair can have:
trait_type: HAIR
value: medium
but on image they can have different color
