I use Keynote to teach programming, which will involve bringing in code snippets. I like them to be syntax highlighted, and to achieve it, I wrote a script to generate RTF that can be pasted into Keynote. The generated RTF's colors and the ones rendered by Keynote after pasting differ. From what I've seen, it's the case that colors look a bit washed out after being pasted. Is there some solution for this? Thanks!

Thanks for the response! Yes, I later realized that VS Code has a built in functionality to copy the syntax highlighting (with color theme), but the problem remains the same. Those colors get washed out. BG getting copied is ok, I just set it to none after pasting in Keynote. My next move to solve this one would be to check the color difference and see if there's a pattern, and may be give it that offset, so that I get the color that I want. I just wish Keynote comes with the support built into it.
RTF is a hard road to travel for stylized text from code, and attempting any color management too. I use the Textastic programmers editor on Mac which offers two Edit menu choices: 1) copy as stylized text, and 2) copy as stylized HTML. Textastic also allows you to use TextMate Themes to customize the syntax highlighting of the code. The application is in the Mac App Store, and there is a free Trial option on the developer's site. It copies the stylized text into Keynote v10.2, but not the editor's background behind that text.
Microsoft's free Visual Studio Code will also copy and paste into Keynote with identical syntax highlighting, but it also carries the background color behind the original syntax highlighted code into Keynote. In my case Keynote v10.2 deposited the code in a Text box, and the black background of the Keynote slide was darker than the dark background of the VSC window.
I don't know if you are pasting code onto a white Keynote slide, but you might have improved color saturation if you used Keynote to experiment with different Text box backgrounds to prevent colors being washed out by the transparent Text box background over a white slide.
Colors wash out when I paste an exported RTF.
