Color is actually a combination of three terms: hue, saturation (intensity), and brightness/tonal contrast (how light or dark a color appears.)
When children learn to identify colors, they learn to identity hue. Hue refers to the attribute of a color dependent on its dominant wavelength. It what makes a color discernible as red, green, etc, and is independent of intensity or lightness.

Saturation refers to how intense a color is. The hues in the color wheel shown above are fully saturated. Most things we come across in nature will be much more dull.

Brightness, Tone, and Value
Brightness or tonal contrast is the range between light and dark. This term is usually used in association with black and white photography, though color photos do have tonal contrast. Think of this in terms of highlights and shadows or blacks and whites. Our ability to perceive these differences in tone is why we can recognize shapes and lines. High tonal contrast photos are primarily light and dark or white and black elements with a sharp difference between them. They are dramatic and strong.
Examples of photographs with high tonal contrast:
Combining hue, saturation, and tone
A strong photograph will often combine many of the above elements.
Here are some examples of photographs that combine contrasting hues, tone, and saturation:
Today we will:
- Take photos outside, trying to capture good examples of how each of the following elements affects the perception of color: hue, saturation, and brightness/tone
- Publish a new blog post with the best unedited photos you took today
