Have no interest in trying to approximate color from renders, that’s hard. Take the plastic chips of RAL 5009, 6009 and 1015 you’ve ordered-not the paper from the RAL deck, this is geekhack not Reddit-and post those in dim light, bright fluorescent light, and sunlight, and post that. Then we can see the color according to the reference standard you’ve chosen. My guess is that green looks dark like your renders in dim fluorescent light, but more green in sunlight. Another alternative is to take your chosen RAL colors and create a diagram comparing those to sets people know-SA nuclear data, camping, the future GMK Taiga / Hunt, etc.
If the reverse dye sub molds look good, I’d figure the manufacturer wants to show off the pictures here on geekhack?
