Thanks! I got to the Filter Editor, adjusted the second flood, and changed some of the blends and got a nice result. I like the flexibility there, but MAN I've got a lot to learn about creating/editing filters. Woof.

I'm a newbie to Inkscape (Illustrator convert). I like the various overlays in the Filters, but I am wondering how I can adjust some of them. For example, I have a solid orange rectangle, and then apply Colorize Turbulent. I'd like to control the color range used in the filter--can I do this?
