Can I use the same paint for exterior window sills and window frames?

[SlightlyJaded]

Logic says 'no'. Victorian Terrace so exterior sills are brick/stone/concrete not really sure but crumbly stuff so would need masonry paint, whilst sash frames are wood so would need exterior wood paint.

But the colour I am painting is a sage green/grey and I would have to get it mixed in two finishes which would be expensive, then tape off the frames whilst I did the sill and vice versa.

Is that really necessary or can I just use one paint for all? And if so, should that be masonry or woodwork paint?

Thanks in advance to any wise person who knows the answer.
