Can I upload a flyer with only RGB files?

Hi, I want to know if I can upload a flyer with only RGB files or does it gotta have the CMYK version?

hi i guess - but i am not sure , this would be better to ask some of the very good technicians here - that this is ok as long as u do not upload the file in print templates …u can create web ones where rgb is ok for sure …

If you use 3D objects in Photoshop that need to be render first before print RGB version is accepted. You need to make a tutorial how to convert to CMYK

Flyer accept only in cmyk colors for print and RGB accept only web category.
