Thanks, that fits with the results I get with my testing! Here's a color table reference that I kinda... over-did (as is my way); it's indexed and includes the 240 main colors plus the 16 greys. Definitely a good resource for anyone who wants to plan color schemes in an image editor before coding them in (feel free to add it to the wiki or wherever, if you like; I happily cede it to you in delayed payment for adding remote component access to the debug card):
Yes, if you change the color palette, anything you've drawn in that color will change to the new color. (It's actually a pretty useful feature; you can create a bunch of 16-color "themes" and switch between them with a single setPalette, changing the colors of everything on-screen.)
