Custom Vision Tool Hue - H Hue is the quality of color that we perceive as the color itself, for example: red, green, yellow. The hue is determined by the perceived dominant wavelength, or the central tendency combined wavelengths, within the visible spectrum. l Hue values range from 0 to 255. These values correspond to a dis- placement along the color spectrum starting from red =0. l At H=0, the color is a shade of red, at H=85, the color is a shade of green, at H=170, the color is a shade of blue. Saturation - S Saturation is the purity of the color, or the grey in a color. For example a high saturation value produces a very pure, intense color.
Reducing the saturation value adds grey to the color. Luminance - L Luminance is the brightness of the color, or the amount of white contained in the color. As the value increases the color becomes lighter and tends towards white. As the luminance value decreases the color is darker and tends towards black. Color Tolerances The color filter accepts any color values that are within defined tolerances. Tolerance values can only be expressed in HSL values. The tolerance range for each H, S, and L tolerance is applied to the defined color. A defined tolerance value is distributed equally above and below the color value to which it applies.
For example, if the Color luminance (L) value is 200 and the Tolerance luminance (L) value is 20, the filter will accept pixels within a range of luminance values from 190 to 210.
