How to add golden tone to sparkles

Question

I have a layered file that consists of a colored background and sparkles over it. There are multiple sparkle layers of different sizes and intensities. The purpose of this file is to generate production images with various kinds of sparkles. I achieve it by tuning background color and sparkle layer opacity. Here's the simplified cropped example:

All layers are of Normal Blending mode, with the exception of the SPARKLES group, which is Color Dodge. And the resulting image is:

As you see, the sparkles have the same hue as the background. But the problem is, for some cases, I need to add a golden tone to the sparkles, so their color would look like (sparkles' form doesn't matter in this example, pay attention to color only):

And I don't know how to do it. I don't prefer duplicating sparkles in yellow, because there are too many layers to duplicate then, and I like the sparkles' appearance in Color Dodge mode - it keeps the original background hue, but just lacks a gold-tone there. Is there a way to add a golden effect in a single place? So it can be easily tuned. I tried to implement it with an adjustment layer, etc. - no success.

Answer 1

For better control with the color I would recommend that you didn't use blend modes to achieve this, but instead used a Solid Color layer with a Layer Mask.

It should be pretty easy to convert what you have now:

• Place a black layer below your "Sparkles" layer. It should now look something like this:
  
• Select > All.
• Edit > Copy Merged.
• Delete or turn off the black layer and the "Sparkles" group.
• In the bottom of the Layers panel, click the Create new fill or adjustment layer and select Solid Color.
• Choose a color (you can edit it later) and click OK.
• Alt + click the Layer mask thumbnail on the solid color layer to enter the mask.
• Edit > Paste in the merged image of the sparkles. It's important that the black background is actually completely black in the darkest point. If it isn't you can use Levels ore some other adjustment to achieve it.
• Select > Deselect.
• Click the thumbnail of the solid color layer to exit the mask.

Now you can choose whatever color you like for the sparkles by double-clicking the solid color thumbnail. You can also click the the mask and edit it like any other grayscale image at any time.

Answer 2

I would...

• copy the composite image.
• Create a Photo Filter adjustment layer
• Paste the composite into the Photo Filter mask
• Adjust Levels on the mask to boost contrast
• Choose the Photo Filter color... and play with the density...

Kind of the same as Wolff's, but the photo filter slider offers a tad more subtle control.
