Sure, here's a simple game that meets your requirements:
Click the Color!
This game will display a randomly blinking color on the canvas. You need to touch the canvas on the displayed color to see if it matches the color name displayed above. A message will appear indicating whether you touched the correct color or not.
Note: Pictograms are not used in this implementation. However, you can replace the color names with pictograms if you have the pictogram images and modify the code accordingly.
