Photoshop and Davinci Resolve hue controls

[Anton Meleshkevich]

I found photoshop hue control (hue/saturation) affects image differently compared to Davinci one. How can I get similar to photoshop hue control results using Davinci Resolve hue control?

I will check tomorrow when I'm back in the office but I'm pretty sure the Photoshop hue control is a global controller similar to the offset wheel in Resolve.

Offset just adds some value to R,G or B channels. Hue control changes H channel in HSL.
Now I'm trying different controls in node with colorspace set to HSL.

If I set hue/saturation effect's blending mode to Hue or Color in photoshop. I get results, similar (or very close) to Davinci Resolve.

I could use HALD to capture photoshop hue control and create a LUT, but I don't want to clip a signal.

Okay, different methods for sure, these's HSL/HSB/HSV/HCL etc... While the hue is changing, Resolve is preserving Y, while Photoshop is preserving Lightness?

What is your Photoshop working color space settings and what is Resolve settings?

Try setting both to Rec. 709 Gamma 2.4.

Also make sure whatever document you're working on in Photoshop is in that colorspace. You may have to set Photoshop HSL to Color Blend mode or Resolves Lum Mix to 0.

When you want to mix colors on the canvas you need to use a low flow, and anything the layer modes can do can be created without the layer modes. There is also brush modes that has more than what the layer modes, like Color brush mode is very useful to change the color after something is painted. It will fill in transparent areas, and not something you would want to do. If you mix colors on the canvas, then there are more primary colors you might need to add. Primary colors go like this Red, Yellow, Green, and Blue. You can not skip over green to mix blue and yellow, because traditionally that would make green and primary color are colors you can't mix. You can't mix and get green. If your flow is kind of high, the paint wants to replace the color, and not mix with it. With a low flow you van mix color, but they will be influenced with anything under the colors unless the base color is filled 100%, then you can use a low flow to add color to it for a mix. Like skin color, and redness of the skin, like a sore spot, or light passing though an ear, showing the blood in the ear as if glows. If you'd like to blend two colors together in general, in a more paint like manner, I recommend experimenting with the mixer brush available in newer versions of Photoshop.
