Here are some from JUCO Photo
Again the palette is extremely limited, note how in the top and bottom images the hues between the blues are very similar. There is obvious tinting in the shadows. For the skin the highlights tend to be yellow while the shadows are more red-orange, and once again the highlights are less saturated than the shadows.

Most people understand digital color as a combination of 3 channels (RGB) when in reality it is more intuitive to talk about them in term of HSL or HSV, that is the color's hue, saturation, and lightness or value. These images focus on understanding the images' HSL distributions. It is common in professional color grading to change colors based on their luminosity value. In Photoshop the masks for adjustment layers are created based on the image's luminosity so the grader can specifically target the shadows/highlights and control the falloff of these adjustments in those areas.
>>3144828Paintings tend to exhibit really smooth highlights and chunkier shadows. Check out (

In paintings the shadows are deep but there generally isn't much in detail there whereas digital cameras tend to capture a huge amount of detail in the shadows (so, reduce the contrast in the shadows further while making them darker). Then the highlights/midtones can be recovered by increasing contrast there while still keeping them bright and not making the shadows too crunchy.
