Hi Mella!
This is Debbie from Soapylove. I would love to help you!
Here is a little chart I created showing how to create each basic color combination:
Here is the general formula for each color you asked for:
1 drop of fuschia and 1 drop of turquoise makes violet
1 drop of red and 2 drops of turquoise makes NAVY blue
4 drops of yellow and 1 drop of red makes orange (Even 1/2 drop of red would be enough to make orange)
These would all be in CLEAR base, and depending on how much soap you are trying to color you may need more of less of each formula. If you are making just a bar or two, put your colors into a small cup, add an ounce of melted soap to the small cup to dissolve the shade, then pour as much as you need into the rest of your melted soap until you achieve the color intensity you like.
Since color is subjective, I suggest playing around and seeing what shade you like best. I think you'll find it as natural as painting with watercolors!
Thanks and have fun!
