Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"I could also do white, play up the fake-angel thing, not that angels in real life have consistent color schemes. Meh." He picks up the black dye.
It offers him previews for the wings and tail (black-dyed flame wings look pretty stylish, if a little too angelic - they turn ghostly white and almost seem made of burning cloud-fluff) but says nothing about his jeans.
"Can't do the jeans, I'll have to handle those myself. Apparently I can recolor the wings, though, I could just go back to my original color scheme and be on fire." He makes dye in his familiar navy blue.
"That's interesting," says Sable. "I don't think that colour of dye actually exists. I wonder how I'd craft it?"
"Nice of you. I have been doing this for eight years, though. It's not that big a deal as long as I prepare carefully."
"Okay. I'm going to start you on very low doses so you'll be okay even if you're allergic. Let me know if you feel anything that isn't on the listed safe side effects list per painkiller and I've got a handy flowchart," he brandishes his computer, "that will tell me what to do if you wind up with anaphylaxis or something; conversely let me know if the ground discomfort gets even slightly better so I can zero in on what if anything helps. If we get to list item number six there is a flowchart item in case of a bad reaction that does involve me touching you, so we can skip that one altogether if you don't want to risk the touching-a-live-thing... thing. Number one -" He has a list and flowcharts; he rattles off some things that are to be expected with this substance. "Say when."
"...Doesn't seem to be doing anything to my ground," she says after a moment. "And was there anything in that list about... everything starting to look slightly purple? Because everything is starting to look slightly purple."
"...There is, uh, absolutely nothing on my list about everything starting to look slightly purple."
"Indeed. So much for them. Let's, uh, wait and see if everything stops looking purple, while I search my medical demonology textbooks with slightly more refined search terms than 'what the fuck'."
