change text color on manga detail page in wordpress madara theme

[Glitch!]

I use the wordpress madara theme, but I could not change the colors on the manga detail page, how can I make a different color than gray and can you suggest different manga themes?

You can do in ccs

.manga-detail {
background-color: #ffffff; /* Pas deze kleur aan */
}
.manga-detail h1, .manga-detail h2, .manga-detail p {
color: #000000; /* Pas deze tekstkleur aan */
}
