The task 34 (from css markers) wont accept my code

whenever I go to check my code, it says that " Your .one CSS rule should have a background-color property set to rgb(127, 255, 0)"
but the .one rule does have this property/value.

  **Your code so far**
/* file: index.html */
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Colored Markers</title>
  <link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
  <h1>CSS Color Markers</h1>
  <div class="container">
    <div class="marker one">
    </div>
    <div class="marker two">
    </div>
    <div class="marker three">
    </div>
  </div>
</body>
</html>
/* file: styles.css */
h1 {
text-align: center;
}

.container {
background-color: rgb(255, 255, 255);
padding: 10px 0;
}

.marker {
width: 200px;
height: 25px;
margin: 10px auto;
}

.one {
background-color: rgb(127, 225, 0);
}

.two {
background-color: rgb(0, 127, 225);
}

.three {
background-color: rgb(225, 0, 127);
}

It’s an easy thing to miss.
