FORTE Template - Change Gallery Arrows Color

Site URL: http://artkartavtsov.com/new-gallery

I'm tried to change color of left/right arrows, but it turn up too hard for my knowledge of css.
And I also want to get the arrows more visible with scaling them more or making them bold of both. 

Is it possible? Thanks for any help!

You can change to white color, add to Home > Design > Custom CSS

a.nav-button.prev-slide, a.nav-button.next-slide {
    color: white !important;
}

 

Thanks! That's work awesome! 
But doesn't work with custom css code which changed black square around the arrow.
Is it possible to change color of arrow and square at the same time with different colors?

It looks like you solved?

Not really. I can change color of arrow with your css, but here is nothing way I can change color/transparency of that black square. It's default black right now.

I'm wondering someone still can help to me with it.
I tried by myself, but my css for change color/transparency of that black square didn't work
