Meanwhile the RPA software/Selenium IDE++ has a command to get the color:
visualGetPixelColor | x,y | var
So in your case you would need to point it to one of the letters of the word.
Or (different method): If the color value can be found directly in the web page source, then you can use sourceExtract and/or storeAttribute can be used, too. But on many pages the color value is not easily available in the page, since it is calculated on the fly e. g. by Javascript.
