I spent a long time looking for this feature (or a similar one) and I was a little disappoint when I didn't find an alternative. I like the way the recolor artwork panel works in Illustrator, I use it mostly for complex multicolored work. I tend to work with more neutral colors or toned down shades that don't strain my eyes and change everything to the final colors when I'm finished. I think every designer and digital artist can benefit from a tool (or a mode of selection) that allows you to adjust color globally.
Creating illustrations (both abstract minimal ones and more complex works) in AD is a really pleasant and seamless experience and a recolor panel would only further enhance. It'd be great if you added a similar feature. :)
