Change colors via hue/saturation dialog

[Darkloke]

Greetings. Lets say i want to recolor this blue potion. Using Hue/Saturation and selecting "blues" i could easily recolor it to green, yellow, red and other colors from (as i understand) "color wheel". But what about other colors? Lets say i want to recolor it to brown - is it possible with this tool or not? I have also tried "selective color" and "color balance" with no avail.

1. So what tool you would recommend to recolor it to brown (i am in particular interested in this color)?
2. And accompanying question - when i operate "blues" in Hue/Saturation - is it possible to make a selection from this "blues"?

In the Hue/Saturation adjustment layer, click the Colorize box. Then you can experiment with the Hue, Saturation and Lightness sliders to get shades of brown. You can see the settings I used here. Then, if you want, go into the layer mask of the Hue/Sat layer and mask away the colorization effect from anyplace where you do not want it.

If you are in the Blue channel of the Hue/Sat adjustment layer, there is no direct way to make a selection of blue from there. Photoshop does have a selection tool called Color Range that selects based on color, but for this particular image your blue liquid is confined to an area with clean edges, so selecting or masking just the blue is fairly easy.

Using the technique that Rich describes above, you can adjust the colors any way you wish using layer masking.

There is another way to do it. I thought of it. Then did it to show you. Colorize could be an option. Color filter is another option. And this is another option.

Open in photoshop and click the toolbar "remove background" or manually mask the bottle. I had to use a hard brush to correct the mask anyway. Then I duplicated the layer. Control plus J. PC (not apple). (I deleted the white layer below the mask) I added an adjustment layer. I did not use hue/saturation at all. I used curves and where it says rgb I clicked on green and blue to change color to brown. Then I added another adjustment layer: color balance. I slid the slider for green/blue on the bottom on shadow/mid, highlights to lighten the brown color. I then used the keyboard shortcut control + shift + alt + E. I disabled all layers below and used the clone tool and spot healing tool to remove some blue smudges. I no doubt could have used hue/saturation to remove the blue smudges but like I said in the beginning of this post I would not use hue/saturation.
Here is a screenshot. And Here is the final image in jpg.

@Korupt - I can always appreciate the many ways you can accomplish the same task in Photoshop. When I approach these types of questions, I have two considerations, ease and edit ability. What's the easiest technique that's the most editable.

Your technique, while it does work, is complicated. You can with this technique but you didn't preserve the luminosity of the liquid. The color is muddy. You have created multiple layers and steps with a stamp visible layer. Then there's the ease of changing colors problem! Note: Try desaturating your image with this technique, it's the only way you can get accurate color with the Color Balance adjustment layer.

Using the easiest and most editable technique with the Hue & Sat layer, it only takes a few seconds to change the color and all with just two simple layers!


Brown with preserved luminosity.


Don't get me wrong here, sometimes there's just not an easy way to accomplish certain tasks, but in this case, I can't see any reason why someone would want to make this task more complicated than it needs to be.

I suppose so.

Many thanks for the answers.

I suppose PS doesnt support "mix colors" technique, used in real painting? I mean you cannot here get, for example, brown color by mixing blue and orange?

Digital colors work completely different from actual paint or colors from an ink printer. In the digital world, most images are in RGB mode, meaning that all colors derive from a combination of Red, Green and Blue. In the digital world, if you mix red, green and blue together, at their full intensity, you get pure white. This is completely opposite to how actual pigments work.

Photoshop can produce roughly 16 million different colors, all of them some combination of red, green and blue. So in that sense, Photoshop does "mix" the three base colors to achieve all other colors. For example, this particular brown (below) is comprised of Red 109, Green 60, Blue 11 (on a scale from zero to 255). However, this mix of digital colors to create brown is very different from what you would need with actual paint to create the same color.
