Doesn't work globally plus it comes to me as complicated with so many settings. Some might like them, I'm more in for something simple and working for all pages at once instead of manually having to set it up for every single page.This review is for a previous version of the add-on (4.9.1-signed).

This is the best working add-on in that category.
There are cases where I would like to have some hue variations within a page, though. For example this review page, setting the stars in the rating did not show. What annoys me the most is that visited and unvisited links look exactly the same, if there is a solution for that I'd be glad to hear it.
The main reason for the limited contrast in the themes of Color Transform is that this ensures that more or less the same result is achieved on dark and bright pages. Simple transformations such as brightness inversion will retain most contrast, but these do not give you control of the resultant colors (for example, dark pages will become bright).
One of the underlying problems is that almost all modern pages use css 'background-image' styles both for backgrounds behind text and for foreground icons/images (such as stars). A theme may now either limit the background colors to a certain range or it may retain the contrast in background images, but it cannot do both.
However, my add-on Colorific contains several single-spectrum transformations that yield higher contrast but less control of the background color. Also, Colorific gives you freely designable themes, so you may try to find a better solution yourself.
For distinguishable link colors, the best solution is to increase the initial contrast in those colors in the Firefox content options.

All-in-all, I love this addon. For a long time I used Stylish for global page adjustments, but the problem with using a global style sheet setup like that is that not all web pages react the same way. It seems that Color Transform, however, reads the individual page data, including the page's own css, and tweaks it to adjust elements to conform to the color transformations set up in the saved color profile. As a result, it doesn't seem to matter how simple, or messy and complex, a page is, Color Transform can do the job and make the page conform to your desired scheme.
But some limitations to the addon make it so that I cannot quite rate this a 5-star addon...
Firstly, while you can choose one of the built-in color schemes, and modify it to customize it the way you want, you cannot save multiple custom color schemes, you can only save a single one. If you change the scheme and save the new customization, the old one is lost.
Secondly, I really wish that the adjustment increments were more fine-tuned. Even using the fine-tune small-increment settings, changing the Hue, Saturation, or Lightness of the color scheme makes some fairly significant and distinct adjustments. On the one hand, it is important to be able to tell the difference between one adjustment and the next, but on the other hand, I personally can distinguish very fine changes in such values, and would like more precise control. Perhaps in the future the developer can add in a third level of adjustment precision for ultra-fine adjustments?
And lastly, I personally would really like to see a built-in site exclusion list. While it is perfectly possible to turn off the change for a given website by turning off the transformations altogether, I would prefer to have it on almost all of the time, and to simply exclude specific rare sites.
I'd also like to make a feature request (other than hopefully seeing the above issues addressed)... I would love to be able to set a "daytime" color scheme, and a "night time" color scheme, and have the addon automatically switch between them (as an option) based on local system time, with the ability to set what times the addon makes that change. I have no doubt that would require a fair bit of additional coding, but I would love to see that option.
Oh, and I'd like to note that it doesn't seem to work with gmail.
Color Transform in its current form won't function in multi-process Firefox which is to be released in several months. I may choose to drop support for Color Transform in favor of Colorific. If you are capable of building a crowd-funding website for new Firefox add-ons / features, please do so.
