Intensity for an RGB color can be calculated by adding up the values of the red, green, and blue components of the color and dividing the sum by three. The formula to calculate intensity for an RGB color is:

Intensity = (R + G + B) / 3

where R is the red value, G is the green value, and B is the blue value of the color.

For example, if the RGB color is (200, 100, 50), the intensity can be calculated as:

Intensity = (200 + 100 + 50) / 3 Intensity = 117

Therefore, the intensity of the RGB color (200, 100, 50) is 117.
