HEEEEEEELLLPPPPPP MEEEEEEEEE

So I have done a dumb thing and have completely bitten off more then I can chew.....

Recently I got involved in a project with a friend to design a mini game and I was given the task of designing the headshots and the sprites. The headshot would be no problem I knew, and I figured that sprite design shouldn't be that hard right?

HAHAHAHAHAHAHAHAHAHA- No. 

Sprite design is hard. It is in fact harder then headshot design. So I decided to download a recommended program called Game Character Hub to design the sprites since I don't exactly have the know-how to design them from scratch. The program itself is awesome!! The colour editing system? That thing is honestly the worst system for colour edit and alteration I have ever worked with. So after several long hours filled with banging my head against a design wall and utterly screwing up my sprites design I have admitted defeat {sorta} and now am putting out a desperate plea of assistance from anyone who knows what the heck they're actually doing.

Please save me from death by rage quit and share with me the great details of how to edit colour in this program!! I desire your grand knowledge. 

Disclaimer: If you just tell me to "move around the colour bars and it'll work" I might have to send my army of vampire llamas after you since that is exactly what I have been doing and trust me when I say that it has not helped me as I try to figure out how to edit skin colour 


EDIT!!!! Since posting this I stumbled around blindly in the program for several hours and have finally discovered what to do!!! Unfortunately it includes colouring each pixel for the thing I want to change one by one.... buuuuut on the bright side at least the half the face isn't brown, and the other half green anymore No more playing around with colour saturation for me~ 

BUT!! If anyone has the idiots guide for Game Character Hub I'd love to see it, or even just some tips and tricks to make things easier I would even loan my fairy llama to youuuuuuu in payment~
