Spraying anything, even rattle cans, is not going to be a possibility due to the fact I'm in an apartment.
I like the idea of a burst of some sort.
maybe like this:
My other concern is that - as this is my last build - I don't want to buy a ton of dye I'll never use again. I like the look of the water soluble aniline dyes from LMII. Could I achieve a decent burst with just, say, amber and red, or amber and brown? I think the amber very thinned could be almost a yellow, through to almost orange at stronger concentration, then a red or brown could pick it there.
hmmm...
lots to think about.
