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 subMobject 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 subMobject 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.
