Each instance of this class represents a color. The class uses the RGB color scheme: each color is a combination of a red, green, and blue components; there’s also a fourth component of opacity. Color objects are immutable.
You don’t instantiate Color directly; instead, you create Colors with the methods on the Color companion object (e.g. Color(200, 150, 255)) or use one of the named color constants in o1.gui.colors. There are also a few methods in this class that returns new Color objects defined in terms of existing ones (e.g., lighter, edit).
This class has an alias in the top-level package o1, so it’s accessible to students simply via import o1.*.
Parameters
- blue
-
the amount of blue in the color, between Color.Min and Color.Max; that is, 0–255
- green
-
the amount of green in the color, between Color.Min and Color.Max; that is, 0–255
- opacity
-
the opacity of the color, between Color.Min and Color.Max; that is, 0–255
- red
-
the amount of red in the color, between Color.Min and Color.Max; that is, 0–255

Attributes
Returns a string description of this color, using preset color names where possible. This description reflects the color’s RGB values and opacity. Examples:

Returns a color with the specified color components. The parameters default to this Color object’s component values, so you can specify just the ones you want to change, as in myColor.edit(red = 255, opacity = 100).
