Keyframe Color Interpolators
============================
Color animation explained in this tutorial and how to use different color
space interpolators.

Creating an animation to animate the actor.
Also cube actor is provided for each timeline to handle as follows:
``Animation(actor)``, ``Animation(list_of_actors)``, or actors can be added
later using ``animation.add()`` or ``animation.add_actor()``

Creating a timeline to control all the animations (one for each color
interpolation method)

Adding animations to a Timeline.

Setting color keyframes
=======================
Setting the same color keyframes to all the animations
.. GENERATED FROM PYTHON SOURCE LINES 81-82
First, we generate some distinguishable colors
.. GENERATED FROM PYTHON SOURCE LINES 82-84
.. code-block:: Python
colors = distinguishable_colormap(nb_colors=4)
.. GENERATED FROM PYTHON SOURCE LINES 85-86
Then, we set them as keyframes for the animations
.. GENERATED FROM PYTHON SOURCE LINES 86-94
.. code-block:: Python
for t in range(0, 20, 5):
col = colors.pop()
anim_linear_color.set_color(t, col)
anim_LAB_color.set_color(t, col)
anim_HSV_color.set_color(t, col)
anim_XYZ_color.set_color(t, col)
anim_step_color.set_color(t, col)
.. GENERATED FROM PYTHON SOURCE LINES 95-97
Changing the default scale interpolator to be a step interpolator
The default is linear interpolator for color keyframes
.. GENERATED FROM PYTHON SOURCE LINES 97-102
.. code-block:: Python
anim_HSV_color.set_color_interpolator(hsv_color_interpolator)
anim_LAB_color.set_color_interpolator(lab_color_interpolator)
anim_step_color.set_color_interpolator(step_interpolator)
anim_XYZ_color.set_color_interpolator(xyz_color_interpolator)
.. GENERATED FROM PYTHON SOURCE LINES 103-104
Adding the main timeline to the show manager
.. GENERATED FROM PYTHON SOURCE LINES 104-114
.. code-block:: Python
showm.add_animation(timeline)

if interactive:
showm.start()
window.record(
