First half (2nd half is on the other side and will have to wait until I get the first half clear coated):
Here are the different dyes used and mix ratios using TransTint for 1Tbsp of denatured alcohol. If using Keda dyes you'd need a lot less drops as they are far more concentrated than TransTint.
#1 Yellow: 27 drops Lemon Yellow, 2 drop Orange
#2 Orange: 40 drops orange
#3 Red: 50 drops Bright Red
#4 Dark Red: 40 Red, 6 Black
#5 Purple: 41 Blue, 7 Red, 1 Black
#6 Dark Blue: 47 Blue, 3 Black
#7 Darker Blue: 47 Blue, 6 Black
Top piece: orange to red fade with sand back:
- Fade with 2, 3, 4.
- Sandback
- Fade again, this time including the 1, 2, 3, 4.
This gives a much stronger contrast, easy to see when comparing to the middle piece.
Middle piece: Indian ocean sunset
- Fade with 1,2,3,5,7. Making sure though to overlap the purple onto the blue (so we never really have a pure blue). Also when overlapping #3 (red) with #5 (purple) the result is a darker than #5 which can look weird, to mitigate that I ended up applying so pure denatured alcohol to pull out some of the dye and brighten the color.
Bottom piece: red to purple fade
- Fade with 1, 5, and 7. Same as above I overlapped 5 completely onto 7 to shift the blue towards purple too, and I also brightened the mixed portion between #3 and #5 using denatured alcohol.
The other side actually is actually similar. I have orange to red fade but wihtout sandback, the indian ocean sunset is the same but doesn't include the bright yellow which is more like Warmoth's Nebula finish, and the red to purple fade was done using a blue I thought wasn't dark enough (#6)
