How do I do this?

[JDRay]

Hello all!

I would like to do the following, see attached image:

• image 1 is the original, image 2 has a blue-ish color overlay: #00abb5
  
• I would like to reproduce the color overlay so I can create an image like #2.
  
• When I add a (normal) layer and use the paint bucket to fill it with color #00abb5 and play with the opacity %, the results are not what I am looking for.
  

So, how do I do it?


Many thanks!
