The background of FE can deliver up to 8 palettes * 15 colors, but to do it, TSA has to be considered and it was hard to make it manually.~
Therefore, we did not care about TSA, we reduced color to 16 colors and used it.~
Therefore, we did not care about TSA, we reduced color to 16 colors and used it.~

Unfortunately, the boundary of the gradation did not come out neatly.~
In this case, you can either correct it by yourself, based on the image of FEBuilderGBA, or give up with 16 colors subtractive color.~
