BulletedList `color` does not set the bullet color

[kjczarne]

Description of bug / unexpected behavior

I tried styling the BulletedList Mobject as fully black and the bullet points still appear white.

Expected behavior

I would expect also the bullet points to turn black.

How to reproduce the issue

Code for reproducing the problem

        t3 = BulletedList(
            "Low Signal-to-Noise Ratio (SNR)",
            "Low contrast",
            "Low resolution",
            color=BLACK,
            fill_color=BLACK,
            stroke_color=BLACK
        )

For now I have worked around the issue as follows:

        tex_template = TexTemplate()
        tex_template.add_to_preamble(r"\usepackage{enumitem,xcolor}")
        t3 = Tex(r"\begin{itemize}[label=\textcolor{black}{\textbullet}] \item Low Signal-to-Noise Ratio (SNR)"
                 r"\item Low contrast \item Low resolution"
                 r"\end{itemize}",
                 color=BLACK,
                 tex_template=tex_template)

[uwezi]

alternatively you can just set the color for the object afterwards:

class bullets(Scene):
    def construct(self):
        t3 = BulletedList(
            "Low Signal-to-Noise Ratio (SNR)",
            "Low contrast",
            "Low resolution",
            color=BLUE,
            fill_color=BLUE,
            stroke_color=BLUE
        ).set_color(RED)
        self.add(t3)

[uwezi]

The reason for this behavior is that Manim does not typeset the bulleted list as an itemize in LaTeX, but rather makes individual rows out of the items and places separately generated dots in front of each line - where the dot itself is typeset without passing any **kwargs on to the MathTex object:

        line_separated_items = [s + "\\\\" for s in items]
        super().__init__(
            *line_separated_items, tex_environment=tex_environment, **kwargs
        )
        for part in self:
            dot = MathTex("\\cdot").scale(self.dot_scale_factor)
            dot.next_to(part[0], LEFT, SMALL_BUFF)
            part.add_to_back(dot)
        self.arrange(DOWN, aligned_edge=LEFT, buff=self.buff)

Gotcha, the workaround you suggested is so much cleaner, thank you!!
