Curves Assistance Request - Recreating a color scheme

[rwh03001]

Hello all,

After reading through the forum Guidelines, searching for posts related to my query, and researching the Curves functionality tutorial, I am still struggling with my current predicament.

I am using Paint.net to alter the color scheme for my company's PowerPoint template background. The goal is to change the colors from the soft blue that it currently is to a soft green (which will be used for internal PowerPoint presentations). I spent some time working on this yesterday and managed to change the picture from this:

to this:

I am happy with this switch. However, there are 2 additional images currently displayed in the blue scheme that I'd like to switch to the equivalent green. However, I cannot seem to accurately replicate my work. There are so many variables regarding the curves and luminosity that I used to create the green scheme above that I am struggling to figure out how to recreate it. Any advice or assistance regarding how I can replicate the green scheme for the remaining two images (shown below) would be much appreciated. Thanks in advance. - Rob

Hue / Saturation would be more suited to that task than Curves. Go to Adjustments -> Hue / Saturation and play with the Hue slider.

...and the effect can be repeated on other currently opened images (or layers) with the keyboard combination CTRL + F.

Thanks for the response. Using the Hue tool first definitely gets me closer to the color I want, but I've spent the last 45 minutes unsuccessfully trying to tweak it so that it matches. Is there anything else that might help narrow down the variables so that I can arrive at the correct color?

Rather than trying to match the other 2 to the 1 you have already done start again and do all 3 with hue/saturation.

Your best bet is to do both again from scratch. That way you'll be using the same technique and settings.

EDIT: They say "great minds think alike". Apparently, so do minners71 and I.

If my company is going to accept the color scheme, it will have to look like something extremely similar to the one I posted above. I basically stumbled upon it by dumb luck because I can't seem to get anything close (if I can, I'll use that or try to tweak it to perfection). One avenue that might be worth exploring is the bar on the bottom. The green is listed as HEX value: 8AB13D. Even though there are other variables at play, is this value of any use in perhaps working backwards to find a good color scheme?

You could try importing the palette from the finished image with this: Palette From Image

Edit: that one only exports the palette , try this one Color Match

What I do is I put both images on separate layers and set the blending mode of the one on top to difference. Then, I adjust the color until the portion that should be exactly the same color in both images (in this case, the stripe across the bottom), is black. I was playing with your images and got pretty close using a combination of color tint, hue and saturation, and color balance. I didn't quite get it perfect, but I was rushed (yes, lame excuse ). If you get close enough, you could just redo the first by repeating everything; a job that involves simply opening each adjustment you used and pressing ok.
