The pointed feathers don't usually show until later (maybe 10 weeks or so), so even a cockerel will have rounded feathers at 6 weeks. There is no "blue-red" in the Ameraucana standard, so it must be a project color, which a lot of people consider EEs until they are accepted. I'm not sure what blue-red is supposed to look like, but maybe the breeder can confirm the sex of your chick by the coloring to date. Sounds like you are hoping for a pullet, so fingers crossed for you! No matter what, it's a pretty looking bird and I'd love to see some more pictures when it gets older.
I am far from an expert on colors. When people are trying to create new varieties (colors) they can get kind of creative with the names too, so you never know!

Rocket certainly has a blue base color and red on the wings, but don't know if there is an official name for this. The closest thing in the standard is Blue Wheaten, but Rocket looks more like a Blue with red leakage. Check out
