Coloring Functions

def set_color(self, color=YELLOW_C, family=True)

~~set_color~~ is used to set the color of a ~~Mobject~~ according to the specified parameters.

def set_color_by_gradient(self, *colors)

~~set_color_by_gradient~~ is used to set the color of a ~~Mobject~~ by gradient according to the specified colors parameters, *color.

def set_colors_by_radial_gradient(self, center=None, radius=1, inner_color=WHITE, outer_color=BLACK)

~~set_colors_by_radial_gradient~~ is used to set the color of a ~~Mobject~~ by gradient radially according to the specified parameters.

def set_submobject_colors_by_gradient(self, *colors)

~~set_submobject_colors_by_gradient~~ is used to set sub~~Mobject~~ colors by gradient according to the specified parameters.

def set_submobject_colors_by_radial_gradient(self, center=None, radius=1, inner_color=WHITE, outer_color=BLACK)

~~set_submobject_colors_by_radial_gradient~~ is used to set sub~~Mobject~~ colors by gradient radially according to the specified parameters.

def to_original_color(self)

~~to_original_color~~ is used to set the color of a ~~Mobject~~ to its original color.

def fade_to(self, color, alpha, family=True)

~~fade_to~~ is used to set the color of a ~~Mobject~~ by fading to according to the specified color parameter, color, and the specified alpha parameter, alpha.

def fade(self, darkness=0.5, family=True)

~~fade~~ is used to set the color of a ~~Mobject~~ by fading according to the specified parameters.
