Changing liquid colour in bottle

[Beermonster]

I have a picture of a bottle of paint and I want to change the paint colour, I've tried hue/saturation and colour replace, both do the job but I need to be able to pick the colour from a colour chart, and those 2 options only let me use a slider

Will this work for you?

1. Duplicate your paint bottle on its own layer and change it to B&W using Image>Adjustment>Black&White
2. Add a Solid Color adjustment layer above the B&W image. Change the layer blend mode to Color.
3. Go into the Solid Color adjustment layer and change the color to be anything you want.

I did these steps in the image below, changing the red paint to green paint. A bit of green appears in the bottle cap, but that can easily be masked away.

Beermonster,

Usually, if you have an image open in Ps, anytime you are in a color-picking option mode, and you move your cursor to the desired color on an image, the cursor turns into a tear-dropper, and you can click to select that color.

Double click the solid color fill adjustment layers icon/thumbnail. This will open the color picker.

In Sam's example, if you have another image file open at the same time, and after clicking on the thumbnail, you can move your mouse over the desired color on the other image, click once, and the color picker will select that color.

See below.
