How to change an image color once on click using CSS alone?

There are a number of ways you can do this: 1) Create a duplicate image of each that is the highlight colour and then using css you can show or hide the 'default' or 'highlighted' image based on whether the list item had the 'current' class or not.

li .hightlight { display:none; } li.current .default { display:none; } li.current .highlight { display: inline-block } 

2) Use background images instead and create 1 image sprite that contains all of these images (default and highlighted) and similar to the above example, when the list item is current change the background-position.

.games-sub-menu li {background:transparent url(path-to-image) no-repeat 0 0;width:20px;height:20px;} .games-sub-menu li.tab1 {background-position:0 0;} .games-sub-menu li.current.tab1 {background-position:0 -20px;} 

3) Use font icons instead of images, and then it would just be the case of changing the colour of the current image.

Font awesome is very popular, take a look. http://fontawesome.io/

.games-sub-menu li {color:black} .games-sub-menu li.current {color:blue} 

Personally i would choose option #3 if possible as it is the easiest to maintain and make changes to. Option #2 is good also but it can be tedious and a pain to maintain. Option #1 isn't advised and although it's pretty easy to implement it's probably the slowest performance-wise.

I think it will solve your problem, make use of css filter

.games-sub-menu li.current { color:#3385ff; filter:sepia() contrast(200%) hue-rotate(150deg); -webkit-filter:sepia() contrast(200%) hue-rotate(150deg); } 

.games-sub-menu li{float:left;display:inline;cursor:pointer;height:20px;line-height:50px;padding:0 38px;margin:24px 0;border-right:1px solid #f1f1f1;font-size:14px;color:#838383;transition:all 0.25s ease-in 0s; } .mg-item .games-sub-menu li{padding:0 12px;font-size:13px;} .bb-item .games-sub-menu li{padding:0 23px;} .games-sub-menu li:hover, .games-sub-menu li.current{color:#3385ff;filter:sepia() contrast(200%) hue-rotate(150deg); -webkit-filter:sepia() contrast(200%) hue-rotate(150deg);}
