MATLAB: Indexing a Text object

figuretext;

Hi all,
I've made a code like below to make a circular array of words.
I wanted to grab certain part of Text objext(variable 'texts' in below) and change the color of it.
% myFields : cell array that contains the words I need to plot.
% numMF = numel(myFields);
x3 = linspace(0, 360 - (360/numFF), numMF);
for i = 1:numMF
    scatter(cosd(x3(i))/2, sind(x3(i))/2, 'MarkerFaceColor', 'white', 'MarkerEdgeColor', 'white');
    if x3(i) < 90 || x3(i) > 270
         text(cosd(x3(i)), sind(x3(i)), myFields(i), ...
            'FontSize', sortidx3(i), 'Rotation', x3(i), 'Interpreter', 'none');hold on
    else
        text(cosd(x3(i)), sind(x3(i)), myFields(i), ...
            'FontSize', sortidx3(i), 'Rotation', x3(i) + 180, 'Interpreter', 'none', 'HorizontalAlignment', 'right');hold on;
        % the code nested in else is for rotation of words since words get reversed.
    end
end
set(gcf, 'Color', 'white');
set(gca, 'XColor', 'none', 'Ycolor', 'none');
texts = findobj(gcf, 'Type', 'text')
%% texts: Text object that contains the whole words in the figure(gcf)
Say, if texts object looks like below, I want to grab only (a1, a7, a10, a17) and chage the color of those. Any good idea for this? Thanks!
texts =  
Text (a1)
Text (a2)
Text (a3)
...
Text (a24)

You cannot do that directly. However if you change Interpreter to tex or latex then you can change the string to use tex or latex notation including color information. https://www.mathworks.com/matlabcentral/answers/278997-matlab-label-with-different-colors-on-the-string-using-latex-interpreter
