Firefox rendering png images incorrectly

[dominatrix1]

I have built a website however I am having problems with the png's in firefox as it is rendering the images as the wrong color. When I inspect the element in dev tool on firefox the images display as the right color which is what I don't understand.

Could someone help?

The PNG itself is fine - the problem is because you've set 'filter: invert(100%)' on the img element on line 121 of marcus.css.

.forest-road{
    color: white;
    max-width: 75%;
    height: auto;
    filter: invert(100%); /* remove this! */
}
