Colombia Late 19th Century Stamp

Hello

I have managed to narrow this stamp down to 1890s Colombia as part of the Coat of Arms series.

The 10 Centavos that I have appears to be on pink paper which I haven't been able to find any reference of. My question is twofold:

1. If this is a known pink paper variety would someone be able to share the Scott number with me please?

or

2. Is this a normal brown variety 10 Centavos which has undergone a colour change because of an ink run in the soaking process/it got wet at some point in time in its history?

Thanks

Michel # 111 (from year 1892) on rose paper. Maybe Scott # 153

Thank you very much vayolene
