LWUIT doesn't support different colors for a label (hence ticker) since that would require quite a bit of processing.

Implementing a ticker from scratch in LWUIT is pretty easy though. Just derive label and override paint as such:

public void paint(Graphics g) {
    UIManager.getInstance().setFG(g, this);
    Style style = l.getStyle();
    Font f = style.getFont();
    boolean isTickerRunning = l.isTickerRunning();
    int txtW = f.stringWidth(text);

    // update this to draw two strings one with the color that's already set and the
    // other with the color you want
    g.drawString(getText(), getShiftText() + getX(), getY(),style.getTextDecoration());        
}
