Each of the rebus works as follows:
A string X is derived from the rebus itself, and a string Y from the overall typesetting (font size, color etc) of the rebus. The answer is then X placed inside Y, since the image literally shows X in (the style) Y. The cute figures below each of the top four images act as definitions for the answer, allowing us to confirm our answers as we progress.
The rebus is L IN DF written in BOLD, so the answer is BLINDFOLD.
P OR E in CORAL giving CORPOREAL.
T IF IC in ARIAL giving ARTIFICIAL.
E TO T in TEAL, giving TEETOTAL.
And there's more!
As hinted by the numbers below, we can take the 3rd, 7th, 7th and 4th letters of these answers to form a new rebus:
So the final answer is:
CT IF IE in RED, giving RECTIFIED.
