Hello raffriff 42
I have written this function based on your luma range script and avisynth overlay internal function opacity tune. It is like a manual RGB problem soluce way in YUV world.
It is possible with it to process manual white balance.
For easy test of this function, in script end, is written a function call script with AvsPmod usersliders use.
Code:
function Other_colors(clip clip, int "limit_lo", int "limit_hi",
\ float "color_red_invert", float "color_green_invert", float "color_blue_invert",
\ float "color_lo_red", float "color_mid_red", float "color_hi_red",
\ float "color_lo_green",float "color_mid_green",float "color_hi_green",
\ float "color_lo_blue",float "color_mid_blue",float "color_hi_blue",
\ float "color_lo_black", float "color_mid_black", float "color_hi_black",
\ float "color_lo_white", float "color_mid_white", float "color_hi_white",
\ float "contrast_lo",float "contrast_mid",float "contrast_hi",
\ bool "show_mask_color")
{
Assert(clip.IsYUV, "CheapColorTemp: source must be YUV")
show_mask_color = Default(show_mask_color, false)
#--------------------------------------------- Masks making ----------------------------------------

xlo_color = limit_lo * 3.0 / 256
xhi_color = limit_hi * 3.0 / 256
mask_lo_color mt_lut(clip,
\ yexpr="x -0.01 * "+String(xlo_color)+" + 256 * ",
\ u=-128, v=-128)

I think that i should get more accuracy with more luma range zones. But i do not know write masktools formulas for this.
Thus i have put in beginng two variable values for enable little mask making modifications.
What do you think of this trial, is it in accordance with yours observations ?
Thanks
