Actual Colors are very Muted

Disappointed in how this t-shirt turned out. I have ordered other shirts previously that turned out very well so I'm not sure what went wrong this time. The colors of the actual shirt are very different from how they looked on the website design space and the proof, as they are different shades, very muted, and not at all what I expected. Perhaps I should have used a white or grey shirt rather than a navy one for this design. Maybe I will try again using different design colors on a lighter shirt as I really like my design.
