The Liquid color filter would be fine if you could preview in its proxy box shapes and photos underneath your targeted text.

Without a live preview of your entire composition, you have to move the proxy box so you can see your composition, and then guesstimate the specific areas that need to be "pushed" up and down. And because the Liquid color proxy box doesn't offer a cursor size, it's still more guesswork.

This is one of the reasons why I wrote the Tips and Tricks tutorial the way I did: to give designers and artists the practice and skills with a manual technique that offers completely predictable results.
