Manim Themes

[icedcoffeeee]

How should themes be implemented, if they were to be at all? There was effort in applying a theme, but looking back, it doesn't seem like the best implementation since it just uses a dict to store colors of the mobjects.

config.theme = {
    "mobject_color": "#343434",
}

Others suggested implementations to include a Theme class which I'm not sure what could be passed into its construct (maybe mobject color)?

class Theme:
    def __init__(self, mobject_color: Color = BLACK):
        Mobject.set_default(color=mobject_color)

Another would be an external theme config file to be used every script. But that might suggest implementing a second config system for themes.

# theme.cfg
Mobject = BLACK
Circle = BLUE
background = WHITE

And currently so many mobjects have hardcoded colors which deter inheritance to change the colors of children classes; which is understandable since we wouldn't want someone who doesn't use themes be greeted with a bland b&w scheme.

Some voiced out the themes are unnecessary and the users should put effort in styling the scene.

Relevant discord discussion

Personally for my projects, I have a special file manim_tweaked.py:

from manim import *

Mobject.set_default(color=BLACK)
config.background_color = WHITE

Which I can import to my main script:

from manim_tweaked import *

class Test(Scene):
    def construct(self):
        self.add(Axes())

and it works fine for me.

I would love to hear more opinions either suggesting a good implementation, or whether theming at this point is even necessary.
