Need to be able to overlay specific colours (with RGB codes) over dark sections of images with true colour results

Hi all, 

I am new to photoshop, and am teaching myself how to create a freshly painted look over an existing image of a home, for clients who want a preview of their chosen paint colour schemes. Given that the colour is what they're wanting to see, the colours that I am filling with have to be spot on.  

To date I have been creating masks for each section of the home (walls, doors, gutter etc), then adding a blank layer, filling it with the colour swatch and creating a clipping mask. I find that Colour blend mode works best in keeping the structure of the image and a true colour for the most part. If it's slightly off on colour I have been adjusting with levels, curves or channel mixer and visually matching it up. 

Where I have a problem is with a dark colour on the existing image. Say someone has a dark front door and they want to paint it in a specific shade of white, does anyone know how I can achieve this please? 

I have been trying with channel mixer to lighten the masked section, then adding that coloured layer overtop as a clipping mask, but it looks so artificial and loses all structure, and is also not a true colour as the client wants to see. 

I am going out of my mind with youtube clips,  google searches and playing around, I know this is possible as we have seen "paint overlays" in the past where the white door (for e.g.) looks perfectly painted, in the perfect colour and structure. 

Thanks in advance!

Hello Adel L,

Firstly, congratulations on using clipping masks, and even more congratulations on using the blending modes.  I'm a beginner too and think of these as a bit too advanced for me. 

I recommend that you stick to just the Curves adjustment layer.  I think you'll suffer less frustration if you build up your skill using that and leave Levels and Channel Mixer for later, possibly much later. 

I find Levels too limited, and Channel Mixer seems to be optimised for converting sensible images into weird images.  Green skies and blue lawns for example. 

You might try converting the original to Black and White and applying your colours to that.  If you are applying your colours to a coloured image, I'm not surprised that you are having a miserable time. 

That doesn't solve the problem of painting a black door white, but the blending modes do include alternatives like Lighten, so it might help to try one of those. 

Hopefully, someone more expert than me will offer better advice.

You can try other blend modes such as soft light, hard light, etc.
In a worst case, but easy, is to paste a photo of the door design and color you want (even adjust color if close). Google image search may find just what you want; check for any legalities for use.

@AdeleL Try this: (from menu) Image, Adjustments, Replace Colors... There is a good course on the process by Matt Kloskowski which was done a few years ago but still apropos to the current version: Mastering Color in Photoshop, which is on the KelbyONE site.  There are several lessons in that course, just scroll down until you find this specific topic... There is also a good written description, "how to" on the Adobe website. It works quite well!

Using this technique you will not lose texture, lighting, or feel of the original surface.
