Yes.
Blue, as in black/blue/splash, is sometimes also called "Andalusian Blue" (because the Blue Andalusian breed was the best known one with that gene at the point people were figuring out that there were two different genes that could make chickens look somewhat "blue.")
Distinguishing "self blue" and Andalusian blue" was at best confusing. Calling the one "lavender" and the other "blue" is a little better, and mentioning black/blue/splash usually helps make it clear which one is meant there too.
