The yellow is not showing correctly on my monitor - it is definitely a clear yellow, not gold. The blue and fuschia look true to me.
Here's the results:
The left column are 1%DOS; the right are .5%. I switched to a smaller brush after the first few rows and there weren't as many blotches. For the next samples I'm going to have to keep an eye on how much dye I'm laying down. I guess there's a limit to how much moisture the paper can absorb!
On the back of each strip:
I'm not sure how I'm going to store these. Maybe page protectors or maybe punch a hole on each end and keep them on a binder ring. It's heavy watercolor paper so it should be sturdy enough for that.
Something for you to ponder - why did finding this make me so happy?
