Py5Graphics.color_mode()

Py5Graphics.color_mode()#

Changes the way a Py5Graphics object interprets color data.

Description#

Changes the way a Py5Graphics object interprets color data. By default, the parameters for Py5Graphics.fill(), Py5Graphics.stroke(), Py5Graphics.background(), and Py5Graphics.color() are defined by values between 0 and 255 using the RGB color model. The color_mode() function is used to change the numerical range used for specifying colors and to switch color systems. For example, calling color_mode(RGB, 1.0) will specify that values are specified between 0 and 1. The limits for defining colors are altered by setting the parameters max, max1, max2, max3, and max_a.

After changing the range of values for colors with code like color_mode(HSB, 360, 100, 100), those ranges remain in use until they are explicitly changed again. For example, after running color_mode(HSB, 360, 100, 100) and then changing back to color_mode(RGB), the range for R will be 0 to 360 and the range for G and B will be 0 to 100. To avoid this, be explicit about the ranges when changing the color mode. For instance, instead of color_mode(RGB), write color_mode(RGB, 255, 255, 255).

This method is the same as color_mode() but linked to a Py5Graphics object. To see example code for how it can be used, see color_mode().
