It sounds insane, but the array that drives it is functionally not that different from the array that individually causes LCD crystals to shift.

I have DLP parts sitting around because they’re cool.

What’s the 4th color on the wheel used for? White minus white… black, yes. But why?

  There is no way that the pictures I’ve snapped can produce the colors accurately. When I look at that small section, it reflects forest green light back to my eye. The light that passes through seems to be muddy yellowish

Woah that color wheel… You can see the cyan, magenta, yellow light reflecting but red, green, blue light passing through to the table, respectively. Such a great example of complementary primaries

  I’m so happy you noticed, the colors cannot be reproduced in a digital photo, when it shines in the sun it’s so beautiful!
