Colors will not transfer

Hey guys, I need some help. Im creating a design in sketch for a logo. However the colors I use aren’t transferring over when I upload images from sketch to web flow. How do I correct this?

Export/Save as RGB colour in whatever format you prefer (PNG/JPG).

Thank you for the advice. Ill try that out and let you know what happens.

Okay I tried out what you suggested and It worked out for me. Thank you again.
