Dell U2312HM Why are these capacitors different colors?

[FluxCap123]

I have a Dell U2312HM monitor with a bad power regulator. As part of the repair I was going to replace the capacitors near the regulator. All 4 capacitors are the same size/voltage but two are brown and two are black (see attached photos). The reference numbers on the two different capacitors are: 1301(M) and 1321(M). Does anyone know what they mean? Can I use the same replacement capacitors for all four?

Any advice would be appreciated. Thanks.

1301 (M) and 1321 (M) are production date 13 years 01 and 21 weeks.
