This companion object of class Color provides methods for creating new Color objects. There is also a small selection of related utility methods and constants.
For many constants of type Color that represent different preset colors, see o1.gui.colors.
This object has an alias in the top-level package o1, so it’s accessible to students simply via import o1.*.

Concrete methods
Creates a new fully opaque Color with the given RGB components.
Creates a new fully opaque Color with the given RGB components.
Parameters
- blue
-
the amount of blue in the color; values outside the 0–255 range are clamped to fit it
- green
-
the amount of green in the color; values outside the 0–255 range are clamped to fit it
- red
-
the amount of red in the color; values outside the 0–255 range are clamped to fit it
Attributes
- Returns
-
the color
Creates a new Color with the given RGB components and opacity.
Creates a new Color with the given RGB components and opacity.
Parameters
- blue
-
the amount of blue in the color; values outside the 0–255 range are clamped to fit it
- green
-
the amount of green in the color; values outside the 0–255 range are clamped to fit it
- opacity
-
the opacity of the color; values outside the 0–255 range are clamped to fit it

the color
Creates a Color specified in terms of the HSI (hue—saturation—intensity) color scheme.

Parameters
- hue
-
the hue (“main observable color”) component of color, in degrees around the color wheel (0–360)
- intensity
-
the intensity (“brightness”) component of the color; values outside the 0–255 range are clamped to fit it
- opacity
-
the color’s opacity; if unspecified, defaults to fully opaque (Color.Max)
- saturation
-
the saturation (“richness”) component of the color; values outside the 0–255 range are clamped to fit it
Attributes
- Returns
-
the color (represented internally as RGB nonetheless)
Deconstructs a Color to its components and returns them as a tuple. Its presence here in the companion object enables us to write things like:
Deconstructs a Color to its components and returns them as a tuple. Its presence here in the companion object enables us to write things like:
myColor match
case Color(r, g, b, 255) => "opaque color: " + r + "," + g + "," + b
case Color(r, _, _, _) if r > 200 => "high in red"
case _ => "other color"
Parameters
