I started this by putting the first bright colors on the leaves/seaweed and then waiting a while (not sure how long - I really need to time this and write down how long it takes)...and spritzing them off (leaving just the paint that dried and removing the paint that was not set).
So I finally got the look - but removed a lot of the paint. No worries...
You just reapply paint, going a bit darker and duller in color to tone down what is left of that bright green - ouch!
for my taste (the photo is NOT that bright lemon-lime green but is warmer than this looks BUT still pretty darned green).
Oh, well, not going to panic (yet), but will remove the masking fluid on the koi and begin on them before deciding what to do with the leaves/seaweed.
No one said this was going to be easy...right? Don't give up on me yet...I think it can be saved...maybe...I hope...
