Ten Corvids In A Trenchcoat

I like to think that colors can change in brightness, mix with others, and appear in certain areas/patterns to give a bit of complexity to the use of colors for communication.

Top left is pretty straightforward- yellow is fear. It's the full body "puffed up cat" kind of fear where it's the ony emotion being processed. A lingering anxiousness would be shown more like a general yellow centered around the chest, while the rest of their body remains the same color. Feelings like a slight nervousness (Like handling a delicate object with big crab-claws, for example) would be shown through a "rippling" wave of yellow overtop of whatever colors are already present, originating from the chest or hands. ((link) this is pretty close to what I imagine (If the link doesn't work, skip to about 2:10) Spooky ocean warning! though if you're seeing this post in the first place I assume you're probably fine with it )

Green is analytical - He does this a few times in-game, and it's what makes the most sense to me. I also like to think it's the reasoning behind a lot of the Architect's... well, architecture. Green is a really predominant color in all of the architect structures / data hubs / machines / etc., so in cultural sense it would make sense for the Architects to be using the color representing their core values. The light blue around his sides is amusement/joy. (I put a little bit of this into my first chapter iirc) This is also based pretty closely to what we see in-game. (I.e. the little wave he does back at Robin, it's silly and playful and I love it sm)

The gray/dull tones (bottom left) are just that- the "muting/dulling" of whatever color it's applied to. The Architect who kind of killed his entire species is a little depressed if you can believe it! A muted blue (indigo, rather than light blue) would be melancholy, and the yellow tint in there is stress/dread. A completely dim gray Architect is basically completely numb, which is distinct from the typical "resting color" that Architects have when not feeling any emotion in particular at a given moment.

Dark blue (Or indigo, bottom right) is sadness. It could also be read as a sense of longing or wistfulnes, or a lot of other nuanced feelings depending on other colors or context clues.

And of course magenta (bottom middle) and that coral-ish color are love, more or less. It's a sense of fondness and deep affection, though Al-an himself is probably under the impression it's more like a loyalty and protectiveness; I don't think he has any real experience with love considering what we know about the network.

The coral color in the center of his chest is something I'll dive into more when I get that chapter out, but I think of it as a flush/heat, like an Architect blush. Orange is added to colors to increase the intensity of the emotion underneath, such as the inclusion with magenta to mean flustered or to red to mean a more heated rage. An embarassed architect would be fully orange, possibly leaning a bit towards pink, red or yellow depending on the specific situation.
