Another way to to invert the hue first then the invert the image color.

All I am going to say is that white text (#FFFFFF) on a light orange-yellow (#FFB62A) button fails the Web Content Accessibility Guidelines (WCAG). I tested that colour combination on contrastchecker.com, and it fails every single criterion across the board. Choose a different colour instead, and choose a contrasting text colour. All the red circles with ...

For a website CTA you should always consider: good contrast between button and background good contrast between button and text it looks like a button or link From there it's pretty much up to you what color to use. In my tests usually the specific color doesn't matter, as long as it fits the three criteria above. In your case, I'd use a completely ...

The question is lately edited from an ambiquous state to a better shape. It demands now explicitly predefinable hue quantization and remapping. The accepted answer gives it for Photoshop. The next is for freeware users. Paint.NET has a plugin filter which does hue and saturation range mappings directly. This task needs applying the filter four times to ...

The answer @Vincent gave is correct in my opinion. I just feel like clarifying a bit (without getting into too many details). A PANTONE Color Book in Adobe's applications is basically just a list of PANTONE colors with corresponding Lab values. (I know because I once hacked my way through decoding them for a hobby project). They are stored in .acb files ...

This is a flawed concept to reproduce because its entirely abritrary where one color ends and another begins. You also talk about preserving tint which makes it even more confusing. That said for your result you might try: Convert to LAB Duplicate the layer and posterize it with 4 Create 4 Solid Color adjustment layers with each of your 4 colors. Change ...

The link you are using (Pantone Color Finder) is not giving you multiple options. It is giving you the exact information you're looking for. Search for one of those colors. It is giving it in C and CP likely because of the fuzzy search it uses. But if you're looking for 637C then use the one that says 637C not 637CP. That gives you the following values: ...

Adobe Photoshop's colour picker offers RGB and CMYK values for different Pantone inks. I'm not too sure how accurate they are, though. Open the colour picker in Photoshop; Click the button 'colour libraries'; Open the 'book' dropdown list and choose the kind of ink--'Pantone solid coated' in your case; Key in the number of your ink, so it will show as ...

As others have pointed out, the logic of this question is a bit flawed, but very interesting nonetheless. My answer is mostly based on RGB/HSB math and I admit that there are many questionable aspects when it comes to percieved color, color profiles etc., but I'll give it a shot anyway. I'm taking the liberty to redefine the question a little bit to be ...

The question does not clarify the purpose of the image, this answer is for an image intended for printing (EPS DCS) In this case, converting an image to only four inks without having the color black, assumes the shadows of that image will be the darkest color, blue. Starting from a CMYK image where there are 4 color available channels and go to menu Image ...

As for me, It works when you reduce the opacity of the black colour to 15%. Most of the time the light effect use screen blending. It works differently with CMYK. so Just reduce the opacity
