Is "RGBA" not a supported colorspace?

Export["test.png", RandomImage[1, {100, 100}], ColorSpace -> "RGBA"]

Export["~/Desktop/a.png", Graphics[Circle[]], Background -> None] ? Or add an alpha channel to the Image before exporting. – Szabolcs Feb 16 '15 at 23:07
@Szabolcs that works, but still kind of weird that RGBA isn't a valid ColorSpace you know? – M.R. Feb 17 '15 at 01:55
