In Storage, black numbers on green backgrounds represent items that do not consume Storage:

 * items purchased with gems"

If I understand, things I buy with gems won't take up space in storage. Some trains (those given as a reward and later used to complete a controct) show with a white background. Those are the ones that can't be sold. Sorry for my confusion.

So, basically, I don't want to sell green labeled items because they will be used, or have been used, to complete a contract, or ones I paid gems for?
