There are so many properties you can set. for example:

plot(1:10);
ax = gca;
get(ax)  % Display what properties we can alter

             ZTickLabelMode: 'auto'
         ZTickLabelRotation: 0
                  ZTickMode: 'auto'

The colors are in the range of 0-1 and in order r, g, b. So for example, red would be [1,0,0]. So to make a font size of 20 with the x labels being red and the y labels being blue, you'd add these lines:

ax.FontSize = 20;
ax.XColor = [1, 0, 0]; % X labels are red.
ax.YColor = [0, 0, 1]; % Y labels are blue.

Note that changing the XColor and YColor change the color of the lines and tick marks as well.

Yes, you can change your XTickLabel or YTickLabel to something that includes latex color specification. https://www.mathworks.com/matlabcentral/answers/278997-matlab-label-with-different-colors-on-the-string-using-latex-interpreter#answer_282116

With relatively recent MATLAB versions, there is also an axes XRuler and YRuler TickLabelFormat property that you can set to an fprintf / sprintf style format string, instead of having to create the XTickLabel or YTickLabel entries yourself. Using TickLabelFormat also has the advantage that if you zoom or pan that the new labels would have the correct entries automatically.

ax = gca;
ax.XRuler.TickLabelFormat = '....'

I tried but not

[Walter Roberson]

The top part holds what appears to be a uitable(). uitable() are not within any axes.

The bottom part holds a plot in which text() has been used, or possibly a graph() object had plot() applied to it. There are no axes labels in the bottom.

If you want to change the color of the text such as the 108 then if you used text() to put it there, you can change its Color property.
