Changing MathTex default color does not change y-tick colour in BarChart

[OldBlood03]

Description of bug / unexpected behavior

Setting the default color of MathTex before creating an instance of BarChart does not set the color of the DecimalNumbers that make up the y-ticks. oddly enough, x-ticks are correctly coloured

Expected behavior

Expected the DecimalNumbers of the underlying numberline to be colored black. Trying to pass in decimal_number_config = {"color":BLACK} does not work

How to reproduce the issue

Code for reproducing the problem

```py config.background_color = WHITE class graphing (Scene): def construct(self): Text.set_default(color=BLACK) Tex.set_default(color=BLACK) MathTex.set_default(color=BLACK) config = {"color": BLACK, "decimal_number_config": {"unit": "k"}} bitcoin = pd.DataFrame({"Date":[2019,2020,2021,2022,2023,2024], "Price (USD)":[8000, 12000, 18000, 12000, 17000, 2]}) nasdaq = pd.DataFrame({"Date":[2019,2020,2021,2022,2023,2024], "Price (USD)":[8000, 12000, 18000, 12000, 17000, 2]}) ax = BarChart( values=bitcoin["Price (USD)"].to_numpy(), bar_names = bitcoin["Date"], y_range = [0,bitcoin["Price (USD)"].max(), round(bitcoin["Price (USD)"].max() // 10,-3)], y_length = 6, x_length = 6, x_axis_config= {"font_size":36}, bar_width = 0.5, axis_config = config ) ax2 = BarChart( values=nasdaq["Price (USD)"].to_numpy(), bar_names = nasdaq["Date"], y_range = [0,bitcoin["Price (USD)"].max(), round(bitcoin["Price (USD)"].max() // 10,-3)], y_length = 6, x_length = 6, x_axis_config= {"font_size":36}, axis_config = config ) grouped = VGroup (ax,ax2).arrange(RIGHT).scale(0.8) bitcoin_label = Text("Bitcoin $",font_size = 20).move_to(ax.get_axis(1).get_critical_point(UP)).shift(UP/2) nasdaq_label = Text("Nasdaq $",font_size = 20).move_to(ax2.get_axis(1).get_critical_point(UP)).shift(UP/2) year_label = Text("year", font_size=20).move_to(ax.bars[2],DOWN).shift(DOWN) y2_l = year_label.copy().move_to((ax2.bars[2].get_critical_point(DOWN) + ax2.bars[3].get_critical_point(DOWN))/2).shift(DOWN) bitcoin_plot = ax.plot(lambda x: 8000 + (x*sqrt(2000))**2, x_range = [0,4.235]) nasdaq_plot = ax2.plot(lambda x: 8000 + (x*(nasdaq["Price (USD)"].iloc[-1] - nasdaq["Price (USD)"].iloc[0] +800) / nasdaq.shape[0]), x_range = [0.15,5.5]) self.add(bitcoin_plot) self.add(nasdaq_plot) self.add(year_label) self.add(bitcoin_label) self.add(nasdaq_label) self.add(y2_l) self.add(grouped) ```

could you please provide an example which does not depend on your external data files - this would allow for quick testing and debugging.

Until then you can check yourself, if setting all the color presets using the following theme solves your problem: https://gist.github.com/abul4fia/353b9a2c3d000088a82175fa64e0ce24

Unfortuantely, your suggestion does not work. I will edit the original post to improve testing as you have suggested.
