multiple hex colors for item name doesn't work

[Jeroen123TC]

if I want to have multiple hex colors for a item name it doesn't work, one hex code works fine.

not working example:
#ffff33Test Winkel#ff9900

working example:
#ffff33Test Winkel

Was just looking on here for something and saw this, for multiple hex codes use the &x&r&r&g&g&b&b format-

For your 'not working example':
&x&f&f&f&f&3&3Test Winkel&x&f&f&9&9&0&0
