Sorry to double post, but I would like to say that I've solved my problem, and I'm wondering if what I did would be useful for other userbars.
I used the cloud effect, using 2 colours, one colour being much darker then the first, but still close to the same colour ( you can change it, but I don't think it'll blend).
Make a new layer, do the same thing with another colour, then erase all the way up to where you want it to show (at this point I made the yellow show here it does because I wanted all colours to have about equal space), then put your eraser at transparent white with like 4 alpha, and erase some from the beginning of the yellow, to make it seem like it's blending. After that, I selected around the tip again, then used the feather plugin at max (functionality?) to make it blend as well as possible. When that's done, rinse and repeat with another colour. The end result is this, what I was trying to do. Now I can put my pokemon on it, add the scanlines, the shine, border, font and etc.
Sorry to waste your time like this, I decided to search for a "soft eraser" on google, which helped me find the feather, which at the same time showed me I could turn the alpha on the eraser down.
Also, for Tl;Dr if this below, is something that hasn't been done, then maybe I could post a tutorial on it. If there's a way to blend more like that, or if someone's done it already, then it'd be nice if you could show me, thanks!
EDIT: I was puting this together for like an hour, lol. Thank you for the input! That seems like a much easier way to do it. I'll try to mess around with it. Looks much neater too, lol.
After playing around a bit, I found out that for my userbars it's better to have it much more colourful, like how I made mine using two colours per part. I made that one rather quick, and I'll need to make it blend more, but if you know what I mean, is there anything that could help me in doing that? I don't wwant to bug you anymore, but if you kinda know what I mean, then... yaaa.
Also, last thing for this mega long paragraph, is there a like or reputation system or something? You've just been so helpful that I want to show my appreciation somehow. o-o
