const hexRegEx = /#[0-9a-fA-F]{6}/$;

Full Stack JavaScript Techdegree Student 13,008 PointsI just updated to the follwing RegEx and i got this error : Bummer: Your regular expression matches CSS hexadecimal color values, but also matches other values. See if you can limit your regex to meet the requirements.
function isValidHex(text) { const hexRegEx = /#[0-9a-fA-F]{6}/; return hexRegEx.test(text);
}
