Overlaying image with brand colour

[beau_mash]

Hi there, please help!

I run a charity and our branding centres around a distinctive coral colour we used in all our images. Previously we've used Photoshop / InDesign for this, making a photo greyscale, then turning up the contrast, and finally layering it with that coral (see photo attached for an example).

I love the ethos of GIMP and would like us to move to it, but I can't quite achieve the same effect. I can do the greyscale and contrast steps just fine (I think), but when I've created a layer in our coral colour and made it part opaque the outcome is different. I'm sure there will be a way to do it, but I'm not sure what layer / mask effect I should be using.

Any help is gratefully received! Many thanks

Try setting the coral layer mode to darken only or multiply either give that sort overlay.

   

As a note this was desaturated using Gimp Colors -> Destaturate -> Color to Grey which gives a good base for the effect.
