Marquee - Every Other Item

hi!  Wondering if anyone can assist me in targeting only certain items in the Marquee Block.  I'm looking to change the font color on the 2nd, 4th and 6th items.  I tried the following but it didn't work 😞. Hopefully someone has a solution!

.Marquee * nth-child(2) {
 color:red!important;
}

Use some code like this

textPath.Marquee-svg-text:nth-child(2n+1) {
    color: red !important;
}

n run from 0, 1, 2...

if you need to target items 2, 4, 6... use nth-child(2n)
