An alternative:
You could modify:
function outHtml = colText(inText, inColor)
% return a HTML string with colored font
outHtml = ['<body bgcolor="Silver", font color="', ...
inColor, ...
'">', ...
inText, ...
'</font></body>'];
end
Note the bgcolor, however the result is not so nice (but you can customize each cell).
Another thing you could do is play with the 'BackgroundColor' property, but it affects all cells or you can customize odd, even.
