I have an image in which I need to identify the following, in rgb values (none of which may include black, white, or grey): 1) The primary two color hues (green and red, orange and violet, etc.), 2) the darkest tint for each of these primary hues, 3) The lightest tint for each, 4) The lightest and darkest blues, and 5) the lightest and darkest yellows. Is it possible to identify these colors in Photoshop? And if not, what’s are your suggestions for accomplishing these tasks? Thank you, in advance.
