Fill confidence band hexadecimal color

Hello!
I am plotting a confidence band using fill, and get an error-message when using hecadecimal color:
I have tried with both 'Color' and 'FaceColor' before the hexadecimal color, without it helping. It works when I use a default color such as 'b'.
Also, when trying just to plot the line (not filling), it works with the html-code.
fill([0:hmax, fliplr(0:hmax)], [upper_bounds, fliplr(lower_bounds)], '#7E2F8E', 'FaceAlpha', 0.2, 'EdgeColor', 'none');
Thanks!

"it did not work with Facecolor either"
Have you checked the documentation of your installed MATLAB version (i.e. not the online documentation). It is quite possible that hexadecimal was not supported in your installed version.

% Define the hexadecimal color
hexColor = '#7E2F8E';
% Convert hex color to RGB triplet
rgbColor = sscanf(hexColor(2:end), '%2x%2x%2x', [1 3]) / 255;
% Define your x and y values
hmax = 10; % Example hmax value
upper_bounds = rand(1, hmax+1) + 1; % Example data for upper bounds
lower_bounds = rand(1, hmax+1); % Example data for lower bounds
% Use fill with the RGB triplet
fill([0:hmax, fliplr(0:hmax)], [upper_bounds, fliplr(lower_bounds)], ...
rgbColor, 'FaceAlpha', 0.2, 'EdgeColor', 'none');

Your approach for converting hex colours to RGB triplets:
% Convert hex color to RGB triplet
rgbColor = sscanf(hexColor(2:end), '%2x%2x%2x', [1 3]) / 255;
never occurred to me.
