Color mixing gonna come with time after many exos spawned.
Here is just some stats after my harvesting this may help some to not give up on them. I harvested around 2500 goo kernel (seed) on Pendromethand under ~1h30(this planet had 20% in the resources tab). If you plant it right away using the maximum yield possible (~3,5 pigments per crops) would end up with ~8750 pigment.
8750 pigment in the processor will equal to 8750 spray cans then you can spray 8750 blocks. Ratio 1:1 without coils. (10850 with 24 coils)
You can mutate them also. The worst scenario it would take up to 13 rounds( not suggested to do this). So this would mean you end up with ~ 2224 Goo kernel(10% seed lost for each rounds) which with you can spray the same amount of blocks (without coils).
I understand some may want paint more block than this, but overtime you will stack the pigments then you have several way to mix them up to get the desired colors like @Stretchious pointed out.
You will have many ways to achieve the desired colors.
- Mutate to the desired colors.
- Mutate to the colors that the mix will end up with the desired color.
- Harvest the mix colors from exoworlds.
I can add up that the thought process behind the lost of seed on mutation is so it doesn’t end up in a endless mutation rotation to the desired colors. So you will have to be “smart” about it and try to mutate to the closest color for your mix.
Keep in mind this is a crop meant for end game.
