Hey Guys,
I want to give each Word in my List box an specific color. My mentor said: its not possible. Now I ask here: is it possible to chose the Color of Listbox text with the RGB system ?

Data(1).name = 'red';
Data(1).Color = [255 0 0];
Data(2).name = 'green';
Data(2).Color = [0 255 0];
Data(3).name = 'blue';
Data(3).Color = [0 0 255];
pre = '<HTML><FONT color="';
post = '</FONT></HTML>';
listboxStr = cell(numel( Data ),1);
for i = 1:numel( Data )
str = [pre rgb2Hex( Data(i).Color ) '">' Data(i).name post];
listboxStr{i} = str;
end
figure; hListBox = uicontrol('Style','list', 'Position', [20 20 100 100], 'String', listboxStr );
That should give you an example of what you want with the following function defined based on Guillame's input above :
function hexStr = rgb2Hex( rgbColour )
hexStr = reshape( dec2hex( rgbColour, 2 )',1, 6);
Obviously if you have a pre-existing listbox from Guide you can just do the usual:
set( handles.listbox1, 'String', listboxStr )
instead of creating a new listbox.

The colours and names are embedded in the strings, so you could parse them:
liststrings = get(hlistbox, 'string');
colnames = regexp(liststrings, 'color="(.*)">(.*)</FONT', 'tokens', 'once');
data = cell2struct(reshape([colnames{:}], 2, []), {'color', 'name'});

Slightly modified example of code Yair Altman posted many years ago:
figure; uicontrol('Style','list', 'String', ...
{'<HTML><FONT color="red">Red</FONT></HTML>', ...
'<HTML><FONT color="green">Green</FONT></HTML>', ...
'<HTML><FONT color="blue">Blue</FONT></HTML>'} );

dec2hex( [r g b] )
should help convert between the two, although you have to scoop up the 3 rows of the result into a single string to put into the html string.

Max, this is not an official "Answer" to your original question. If anything, it should have been a Comment to some other response.

Please don't keep adding new questions as answers, it is confusing.
You can define the colour of independent static text objects easily enough (or indeed any independent objects like that if they are predefined).
If you want to have different coloured backgrounds or text in a listbox or uitable or similar though then I'm not aware of any alternative to using html and/or the underlying java UI programming as discussed in previous answers.
If you can explain which element of the suggested solution you are having a problem with we can assist further on that.
