Hot Full Carousel

Hi, sorry for my english.

i bought "explorer" template. my site bankingexpert.ru

In "Hot Full Carousel" (top of site) i can not change color of button (switch slide) from white to green (I change value of "Button Color", but in not work). Also i can not change color of "Heading Text" (i not find it value in module menu, may be it value i can find in code?).

Please help. I need blue "Heading Text" and green "Button Color".

Thank You!

For logo text in layout.css:

.sparky_logo, .sparky_logo a, .sparky_logo a:hover {
line-height: 32px;
color: #fff;
}

For carousel navigation buttons you have this images:

templates/hot_explorer/images/custom/right_arrow.png
templates/hot_explorer/images/custom/left_arrow.png

Thank you for buttons.
But i want to change "Heading Text" in Hot Full Carousel.
Please open attached image

That is defined in layout.css:

.mp_header1 h2 {
color: #fff;
text-shadow: 2px 2px 0px #000;
}

Thank You!
