Why are there Different color TRD bedside stickers

I noticed that on the exact same truck there are different color bedside stickers.
For instance I own a 2017 white DCSB TRD Off Road 4x4 and the "4x4" text on mine is Red. Then today I saw a dark Grey DCSB TRD Off Road 4x4 and the "4x4" text was light grey.
Does this mean anything else or just for the color contrast.
Looking at google images the Blue and Red trucks also have the light grey text but the Quicksand and light Grey have the Red text.

 

Maybe because different colored tickers look beter on different colors of paint?

 

You answered your own question. Different sticker colours for different paint jobs.

 

Depending on the color is the Hp that the sticker will provide.




JK on the real is just for color contrast.

 

The quantity also plays a factor...anywhere between 5 and 50hp I've heard.
