Jut looking for some advice on how everyone here colors their soap!

Iv'e been experimenting with "liquid color dispersions/brites", but can never get it right!
For me i'm pretty sure its a heat issue / soap not insulated enough, but every time i end up get a powdered / uneven color, even with swirled soaps! (made the infamous mistake of swirling on top of soap - didn't go throughout the soap lol)
Anyway does anyone else have any similar issues? Are powdered colors/ultramaries/ oxides more reliable for producing an even color?
Still have the rest of the color set to use up....lol - then likely going back to natural soap/uncolored
