# Proxy for org.eclipse.swt.graphics.Color
#
# Invoking `#swt_color` returns the SWT color object wrapped by this proxy
#
# Follows the Proxy Design Pattern
class ColorProxy
include_package 'org.eclipse.swt.graphics'
# Initializes a proxy for an SWT Color object
#
# Takes a standard color single argument, rgba 3 args, or rgba 4 args
#
# A standard color is a string/symbol representing one of the
# SWT.COLOR_*** constants like SWT.COLOR_RED, but in underscored string
# format (e.g :color_red).
# Glimmer can also accept standard color names without the color_ prefix,
# and it will automatically figure out the SWT.COLOR_*** constant
# (e.g. :red)
#
# rgb is 3 arguments representing Red, Green, Blue numeric values
#
# rgba is 4 arguments representing Red, Green, Blue, and Alpha numeric values
#
