Warning: this is long
Ok, this is inspired by a conversation that @omegastation was having, regarding the Asari and their possible discrimination amongst themselves because of skin colour. Aria T’Loak came up, and this is something that has bothered me since ME2 came out, so bear with me.
Aria T’Loak is blue.
We meet her in Afterlife, where all the lights are red/pink, and it is really a simple matter of colour reflection. When you put something blue under a reddish light, the human eye perceives it as purple (colour mixing 101: red+blue=purple).
These screenshots have not been manipulated except for cropping and resizing (and the rather obvious green highlighting line…). Follow me. As you can see here, the part of her face hit by the lights is purple, whereas the side of her head which is not, and the rest of her neck and her body, are clearly blue.
When we see her in Purgatory, where the lights are blue, she looks incredibly blue, because she is blue under a blue light. Please note that the collar of her jacket, usually red, is now purple because it is red under a blue light. Magic!
Just a couple of notable examples of this phenomenon happening to other Asari: here is Morinth in Afterlife, under red/pink lights.
And here she is, back at her apartment, under neutral lights.
Here is Tela Vasir under some yellowish lights.
And here she is under neutral lights.
And oh look! I found some yellow humans and some red humans and some neon pink humans!
Now you can take this shitlong information thingie and do with it what you will. As far as I am concerned, Aria is blue. :)
