So, a discussion recently about race-stuff attached to Stargate: Atlantis made me realise something.
See, there's a thing, where certain people - usually awful people - claim they "don't see colour".
Because apparently they are stupid, and believe that it shows how totally not racist they are if they claim that they lack the ability to distinguish wavelengths of light. Or that they don't look at anyone who isn't in a mirror, and therefore do not in fact notice what other people look like. Or something.
I, being possessed of reasonably functional eyes, do see colour.
However, what I don't have is visual memory. I do not have the ability to visualise things in my head, to call forth images in my mind. (The name this is acquiring is aphantasia, because it's apparently quite new that we all found out It's Not Just Us.)
Consequently, I discovered, for background extras who don't get lines, who I don't look at enough to note things about their appearance?
I don't remember colour.
I have this vague sense that I think the Athosians are sort of generally mixed in terms of racial makeup, but all I can actually remember about them is that they exist.
This is a weird feeling. The set of impressions I mentally catalogue about a person usually includes things like that. I'm terrible at remembering faces, because I can't call the image of someone to my mind. Skin tone is one of the few distinctive features about a person I can readily catalogue. (Skin tone, hair colour, hair style, build - these are the things I can tell you about someone I've met a few times. I can't draw a portrait without a picture or model, though, no matter how well I know someone. I can tell it looks wrong, but I can't tell what would be right.)
