theme-tweaker-lite

Spent an hour trying to find the exact bit of CSS code to change. Fail. Theme tweaker lite let me do it in two minues. Great little plug-in

This plugin effectively identified the colors in my theme, but it didn't work completely when I tried to change the colors. I tried replacing a red with a blue, but I still had 80% of the red (on my homepage) remain as red. However, approx 20% (of the times where I had words/icons in red) did actually change into blue, though. I was using a child theme of the Specia theme in Wordpress 4.7.

I really like this plugin, but I wonder if there is a way to use it without seeing so many ads. Buying Pro, maybe? HELP
