What does the green and gold colored shipped icon mean?

[tuppshop]

under "sold with paisapay" tab, the seller could see the status of sold items.

I was wondering what does the different icon colour for shipping status means , I could see Blue, green and gold coloured shipping icon.

Orange means, fast ship status under review.

Green means, eligible for fast ship discount.

Blue means, not eligible for fast ship or shipped outside powership.
