Adding to Color Channels
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Explore adding values to each of the HSB and RGB color channels to adjust an image. Each slider adds the value shown to the corresponding component of each pixel in the image. This is also an example of the use of three-dimensional slider controls. The HSB control sliders correspond to hue, saturation and brightness. The RGB control sliders correspond to red, green and blue color channels. The rose image is from [1].

Details
The "HSB" slider goes from 0 to 1 so that the hue cycles through all options just once. Going from –1 to 1 would cover the range twice.
