Working on blending modes to make dynamic weather and day cycle.
Just made a simple blending into color.
Working with a 15-bit colors, 5 bytes for each channel, meaning I have 32 intensities for red, green and blue channels. What I do is simply looking for color in each palette cell, when apply mathematical operations on the color and send the result value back to the cell. On this screenshot I find average value between each color and blue, this can be used for making an overcast weather effect. I also want to add some blending modes so I can adjust picture contrast, vibrance etc. on the go and to apply different cool filters.
