hard to pull off highlights on a guy without looking a little gay but you do it well. I think you're right, blond is definitely pushing it. I like the red. blue might be a bit much, a little overwhelming? plus it looks like you might have to bleach your tips and THEN dye them, otherwise it wouldn't show up too well? I don't know maybe you already do that, maybe you don't have to.
I like guys with highlights, but not bulging where it's more like a hair color than a highlight. I was actually impressed with yours. I think blue would do well, but blonde? Hmm, I could see it, but I have a soft spot for blue.
