how to render image out with less than 10 colors

[coilbook]

Hi Is there anyway to render an image with less than 10 colors because it will printed on T shirt and they allow max of 10. I know you can save final image as gif in Photoshop and chose 10 colors but it looks terrrble especially greens and yellows
Does octane allow this or special camera filter ?
Thank you

Not sure if this is even possible with octane. I would use some posterize filter in photoshop or other compositing software.

you do that in photoshop, save for web and pick number of colors there.. it works pretty well
