Right, uh, so, sunlight's going to have, like, hydrogen lines in there, but the larger problem is that it's missing a bunch of blue from how the air scatters that blue light all over to form the daytime sky.

Firelight plus metal heated white-hot plus, ideally, metal heated blue-hot, if you superposed those colors, and got realistic rainbows from the illusion, would probably work for the light source?  Maybe there's something here about, if you've seen a real thing, you can make an illusion of that thing.  But if you've only seen an illusion, you can only make an illusion of how a thing looks to you, because that's what an illusion is... maybe... if that made any sense, or rather, if it made the correct amount of nonsense for magic.

Keltham has a feeling regardless that Carissa might be well-served by just messing around with this until she can control the light spectrum of illusionary light period.  Get her magical control to where she's controlling the rainbow underneath the illusion, not how the illusion looks to her.  That will plausibly be the equivalent of a Spellcraft exercise for this, and might be preliminary towards being able to Prestidigitate chemical properties.

Though he doesn't actually know the two manipulations would go through a common route, he's just guessing.
