Hues

Below is the table that show the Hues color in respective angle on the Hue Saturation Value model.

The graph show color hues and its corresponding value of red,green and blue .

Changing Hues

Color of the image can be change by rotating the hues to a specific angle. This rotation change all the respective color to the corresponding color on the Hues Model. For example if the original color is red(0°), it will corresponding to yellow(60°) upon +60° rotation, similarly if the original color is yellow(60°), it will correspond to green(120°) upon +60° rotation.

effects of color hues on Ang Pow

Note the changes of color by rotating the hues. While rotating the hue towards the positive hues angle, the red Ang Pow changes from red(0°) to orange(+30°) to yellow(+60°) to green(+120°) to cyan(+180°); while the green grass from green(0°) to cyan(+30°) to blue(+60°) to purple(+120°) to magenta(+180°). However if rotating towards the negative hues, the Red Ang Pow changes from red(0°) to magenta(-30°) to purple(-60°) to blue(-120°) to cyan(-180°); while the green grass from green(0°) to lime green(-30°) to yellow(-60°) to red(-120°) to magenta(-180°). The black of the background and the white of the wedding dress do not change much in perceivable color. Changing the hues changes color with higher saturation.

The example of color changes on a hello kitty ang pow by manipulating the hue angles. Notice that lighter white color do not change as much as other more saturated color.

Below is the expected color by rotating the Hue towards positive angles (+30°, +60°, +90°, +120°, +150°, +180°).

Below is the expected color by rotating the Hue towards negative angles (-30°, -60°, -90°, -120°, -150°, -180°).
