Red Function: r*0.5 Green Function: b Blue Function: g Red Function: r Green Function: g Blue Function: b Note: This effect is half broken in 0.45! The original values are overwritten by the new ones, which means things like the last example won't work as expected. The resulting RGB values are automatically clamped. r, g and b are the normalized values of the red, green and blue channels. Use More Light if you want to brighten up black areas as well.Īllows you to evaluate different functions for each channel. Channels with a value of 0 remain unaffected. Brightens the color(s) by dividing each RGB channel by 0.9.
