Learning colour in mandarin

Since we are on the theme of Rainbow for these 2 weeks. I introduced some Chinese word for colour to Javier. Beside that, we also did some hand stamping on the different colour sheet. After stamping a few colours, he refused to lend me his hand anymore. :P So I just painted the colour on the colour sheet while he looked on. After showing him the word cards for a few times, he was able to pick out the right card (most of the time) for the individual colour sheet when I presented him with 2 word cards to choose.
