I know now how to get a channel :
$image->get_channels
Do you know how to change the color of this channel, please ? I don't find it..
Best regards
What do you mean by "change the color"? A channel is a monochrome thing... This said, a channel is a "drawable" so many "Color tools" work on it (as if it were a layer): Levels, Threshold, etc...
