1. Click on the parrots to see the name of a color and listen to its sound
(It seems the sound works only with IE).
2. Click on the corresponding image (of the color)
If you are wrong, the image disappears and you get an error point (Número de errores).
Click on another image. (You can click again on the juggler if you want).
3. If you are right, the word appears below its image.
4. Repeat step 1.
Note: You can increase or decrease the number of images (between 3 and 9) by clicking on the + or - signs)
