I was told years and years ago that your dried watercolour paintings could have the same intensity that they did when wet if you applied a coat of Gum Arabic.  It was only yesterday that I tried it for the first time on these samples.  I hope that you can see that the left half of the little heart painting is deeper than the right.  And, I painted a stripe in Gum Arabic down the middle of the second one.  Quite effective!
