You need to pair your word items / item numbers with the desired display colors. For the sake of example, suppose you have 4 words and 3 display colors -- you want to display each word in each color exactly once, i.e., you have 4 x 3 = 12 combinations:

<block myblock>
/ screencolor = black
/ trials = [1-12 = mytrial]
</block>

<trial mytrial>
/ ontrialbegin = [values.worditemnumber = list.worditemnumbers.nextvalue; values.wordcolor = list.wordcolors.nextvalue;
    text.word.textcolor = values.wordcolor]
/ stimulusframes = [1=word]
/ validresponse = (57)
</trial>

<text word>
/ items = worditems
/ select = values.worditemnumber
/ txbgcolor = black
/ fontstyle = ("Arial", 5%)
</text>

<item worditems>
/ 1 = "Bird"
/ 2 = "Cat"
/ 3 = "Dog"
/ 4 = "Eel"
</item>

<list worditemnumbers>
/ items = (1,1,1,
    2,2,2,
    3,3,3,
    4,4,4)
</list>

<list wordcolors>
/ items = (blue, green, white,
    blue, green, white,
    blue, green, white,
    blue, green, white)
/ selectionmode = list.worditemnumbers.currentindex
</list>

<values>
/ worditemnumber = 1
/ wordcolor = black
</values>

<data>
/ columns = [date time subject group blocknum blockcode trialnum trialcode response latency correct stimulusitem values.worditemnumber values.wordcolor]
/ separatefiles = true
</data>

Hello,

thanks a lot, that helps. I hope I can expand it to my four conditions, but that should work. Any suggestion why values.wordcolor gives me numbers instead of color labels, e.g. 4278255360, 4294901760 and 4294967295?

Best regards Jens

The internal representation of colors is ultimately a numerical value (not a label), hence values.wordcolor is numerical.

Hello,
ok, understood. Thanks a lot. The extension to four categories of words works. :-)
