So this is Wet n Wild Fast Dry Gray's Anatomy and Square Hue Desert Storm, from the 1990s collection:
I think that both of these are current colors - Square Hue now carries a small selection of single bottles on its website, and Desert Storm is one of them. And I didn't re-check today, but I'm pretty sure Gray's Anatomy was still current the last time I checked, at least. Even if WnW has happened to drop it since then, it should still be findable.
(Huh. Square Hue actually calls Desert Storm a gray or greige - i.e., gray-beige. It doesn't look a bit gray to me,, but I might buy greige as a way of saying "slightly-gray beige." Look at it next to Gray's Anatomy, though - it's just... not gray.)
