header text color change module to module

I am looking to create a number of custom landing pages for PPC traffic.

a) The image darkness of the custom paralax header image at the top of each page ultimately determines whether it the fly-in text will pop better as black or as white. Currently text is default white. With the below custom header html, what additional code can I insert to modify each header for ideally a custom hex text color? Ideally I can clarify the desired color for the regular text and then the desired color on rollover.

b) What code would I use to have a small png image fly in, just prior to the call to action "shop now" button?

<p><img src="images/AGB/landingpages/lollipoponesie/lollipop-heroshot-parallax3.jpg" alt="" class="parallax-img" /></p>
<div class="gkPage">
<h1 data-sr="enter bottom and move 50px">2-4-1?</h1>
<h2 data-sr="enter bottom and move 50px and wait .15s">put this in here</h2>
<a href="index.php/our-products" class="dark btn-border" data-sr="enter bottom and move 50px and wait .3s">Shop Now</a>
</div>

Hi

a). Can You please show me directly which text You have in mind ?

b). I believe data-sr="wait .5s enter left" or something like that, but You can find instruction on this plugin developer https://scrollrevealjs.org/
