Mortar used to reset ridge tiles too light

Hi, We are having a velux only loft conversion done in a top floor flat of an 1870s semi-detached house in London. While doing the work we have felted (it was tiles only) and redone the roof. The contractor seems to have done a neat job with the tiling and the ridge tiles but has pointed the ridge tiles in very light colour sand and cement mortar which does not match old or next door's in colour/tone. When I raised this after first ridge was completed they said it would weather and also dying the mortar would weaken it. I feel a bit fobbed off and our neighbours have already raised the issue: is this normal practice or should they have made more effort to match the darker colour of the adjoining roof? If we insist, is it a lot of work to re-do the ridge tiles (remove mortar and reapply with more suitable coloring)? Are there any dyes available to achieve a better result without re-doing the pointing? Cheers!
