Pointing problems

[beefcat]

I have just repointed a small section of a wall and the colour is greyer than expected!

I used a 6:1:1 mix of building sand lime and cement as I found lots of sites advising this. I did small test bit earlier in the week and the colour when cured is a pale yellow what I want. The latest section I did used exactly the same mix but is grey. It has been 3 days and is a bit lighter that the first day but no where near the other colour I have. Should I expect it to get lighter as it has been a bit damp recently? If not what could have caused this?

I was very sure to measure accurately the mix and if I hadn't mixed it properly then I would expect uneven colour but the area is all the same.

Any help advice greatly appreciated.

Thanks

The sand has more influence on the colour

It is all from the same batch of sand cement lime etc.

was the test panel a different depth to the main bit? was it put in wetter? did it dry very quickly? there are a lot of factors that can change a colour.
