There's been a good discussion about mixing color, which often leads to discussing what colors you use in your palette...often leading to "palette theory" and what some of us prefer, experiment with and what the greats have used over time.
Anyway, just thought it might be interesting for people to post a shot of their palette, for both learning and curiosity. Posts of "traditional" or Master's palettes you may have are welcome as well.
So here's mine (not a great shot as it was in a dim TV studio)
Note: I hardly ever touch Viridian - actually there as a sky color mainly. Also I add black when doing my still lifes and some high chroma/crazy colors when I head to the ocean or I'm going to be painting along a stream (pthalos mostly - basically I carry them with me all the time but don't have them on the palette typically).
