Not much of sale and nothing to do with colors. Even if they are clearing them out at 50%, IMO, ash catcher will remain same for another 10 years or more looking back at the previous design changes and trends.
We have seen much bigger sales before on the master touch at $99, WSM at half price( I think they were clearing them out at $199) and Walmart huge clearances on Weber products over last 4 to 5 months( eg. deluxe Pizza kettle at $40, wsm, and kettles, etc.) ... how do you account for all those big sales including half decent sale on summits. Not to mention these sales on OTG and MT are not that huge.
