Color the drawing from your Memory

Can you memorize a couple of colors for a while and recall everything again?

Here's an app with dozens of drawings.
All these drawings will have colors at the beginning, and the colors will fade away after 5 seconds.
You need to memorize the colors, and recolor the drawing from your memory.

When you finish the coloring, you will see a message saying the time you took to finish the task.

Ofcourse, there are options available to peek into the original colors, or even restart the game from scratch.

Please send me suggestions and love so that I can improve this app more.
