Hi there! I definitely love tags and colors from some time. 
Maybe it's a natural need for colors in this dark times...
Anyway, I had so much fun with this tag and hope it will
inspire you to try out some vibrancy on your projects. 

I covered the tag with Distress Oxide Antique Linen ink + water. 
Stamped the hearts from Accessorize set with brown Archival
Started to color the hearts and highlighted them using oil pastels 
of similar colors. 
Finally I played a bit with the shading using Distres Oxide 
Walnut Stain ink and a water brush. 
In the end I sprinkled the whole tag with white paint.
