The Lifestream Red style set is now complete. It is not actually completely red; neither are the other style sets completely the colours they claim to be, but in this case it's a lot more obvious, which I'm assuming is because red is the bottom of the visible light spectrum. I tinkered with it a bit but this was as good as I felt like making it look. I would've had to edit the images with a lot more than just hue alterations to make it look better.
As for the hot thread problem, since no one specified a solution, I just made them green, because green is a colour that stands out nicely.
By the way, if anyone wants the settings I applied to the original images, here:
Blue: +35 hue (also specifying -35 hue to the colour of red for hot thread images)
Purple: +105 hue (also specifying -105 hue to the colour of red for hot thread images)
Red: +180 hue (also specifying -60 hue to the colour of red for hot thread images)
I'll work on the gold style set tomorrow, maybe. For now I'mma go make cookies.
