Welcome to the gum community. The print is very nice. You got the sun exposure/development nicely worked out. FOr a tricolor get a nice intense yellow. A number of them have been sugested here. If you so desire you can print another blue layer just for the shadows (shorter exposure).

Subject: First tricolor gum
OK, I tried a tricolor gum today with the intent of getting true color. Using 1:1 gum/dichromate ratios and sun exposures of 3 minutes and 30-60 minute development, I ended up with this:
My guess is that I'm not putting enough pigment in my mixes...especially the blue pigment.
I used Prussian Blue, Warm Sepia, and Anthraquinoid Red...all Daniel Smith watercolors.
Insert movie times and more without leaving HotmailŪ. See how.
