How can I assign Keyboard keys to colours?

Hi,

I need to assign colours to Kb names as I am creating a stroop task script with Psychtoolbox.

This is a part of my script:

WordList = {'blanket', 'garage', 'shampoo', 'handle', 'sofa', 'curtain', 'switch', 'bathroom', 'vase', 'hallway', 'duster', 'lounge'};

rgbColors = [1 0 0; 0 1 0; 0 0 1];

rng('shuffle')

%Improve portability of the code acorss operating systems

KbName('UnifyKeyNames');

% Specify key names of interest

activeKeys = [KbName('LeftArrow') KbName('RightArrow') KbName('UpArrow') KbName('Space')];

% Restrict the keys for keyboard input to the keys we want

RestrictKeysForKbCheck(activeKeys);

% Suppress echo to the command line for keypresses

ListenChar(2);

%Assign Kb to colours ??????????

How can i pair the Kb with colours? For example, if it appear a word in yellow the participant has to press Kb 'Uparrow' and so forth.
