Blue SSJ

I don't think there's an actual mod for it but you could download Yusion's Super Saiyan God Blue Addon if you only care about having blue hair that is, you could always download his full mod if you're interested.

Once again if you only care about having blue hair, just download the Super Saiyan God Blue Addon , you only need 1 file that's in the package, which is

HUM_000_Hair.dyt.emb

For some reason he only made one for the first hairstyle but these are just the modified colours for our CaC's SSJ hair so if you want the blue hair to apply to all hairstyles for your CaC, you could just rename this file and overwrite the other HUM_XXX_Hair.dyt.emb - files, since there are 12 hairstyles for your Cac if I recall correctly, you could theoretically just rename this file each time as follows

HUM_001_Hair.dyt.emb
HUM_002_Hair.dyt.emb
HUM_003_Hair.dyt.emb
...

If you want the colour to apply only to your CaC's current hairstyle, then try to find out which hairstyle you're currently using for your CaC

Hairstyle 1 = 000
Hairstyle 2 = 001
Hairstyle 3 = 002
...

If you want this to apply to Female CaC , I guess you could just rename the HUM-files to HUF-files I assume.

Anyway, repack your cpk and you should now have blue hair when transforming into a Super Saiyan.
