slate coloured paint (nutural babgor)

    do I have to make this up myself?
    I went into B&Q and they scanned my piece of slate that I brought in .But the result was unsatisfactory as the slate was naturally multicoloured -grey but not really uniform.
    If I have a go at mixing it myself would I succeed if I started with an approximate grey and added bits of black and white - or would I have to add bits of blue ,reed and green?

    (The reason I need to do this is that I have accumulated bits of silicon (or similar) between the slates as a way of keeping out the rain but they are a little unsightly now as they (the silicon -not the slates) seem to have bleached with age and stand out too much.)

    ps the subject is badly written -sorry I can't edit it either- it should read natural bangor and not nutural babgor....

    A paint can't be two different colours like your slate. The machine in B&Q probably picked up the grey that was nearest. Chances are you will never get a perfect match.

    would a plan of action be to scan it twice or 3 times , get 2 or 3 different results presumably and then mix the colours?
    Is it possible to go to a place like B&Q and give them a set of colour numbers like you see on a computer imaging programme which they can punch into their paint making machine?
    I am guessing though that with a palette of green ,blue and red it might be a doddle to mix any colour approximately by eyesight.

    I worked the dulux colour matcher for years.

    Generally what i used to do regardless of what i was scanning was to scan it 5times and then go with the most frequent result, generally a minimum of 3 in 5 hits to be sure.

    Mixing the colours is not a good idea, because if for example (and im using this as an exaggeration) you had a jet black material with small white spots, the predominant colour i black, yet if you mix the white with the black you have grey - which is a colour not on the material at all!

    You need to get 2 or 3 tiles and get them to do the scan at least 5 times on each - this way you have the best chance of getting the colour you need. It wont be exact im afraid, but hopefully close enough
