Is this baby blanket too girly for a boy?

I have been making baby blankets for all of my cousins. I typically try to stick with rainbow-y colors, since I figure that is gender neutral and it makes for a pretty blanket.

When I purchased Caron Baby Cakes in the Retro colorway, I thought it was gender neutral-ish. However, after I crocheted it up, it looks a lot more girly than I expected.

Not that color should ultimately matter. It is a free hand made blanket. However, the cousin I’m gifting it to is more traditional than me, so I’m not sure if she’d appreciate this for her baby boy.
