Whisky Labels

But why do they use is black, red, blue labels etc and not purple, yellow, and so is their importance for the colors black, red, blue etc when it comes to whiskey, is it in do with the color was used?

There is no significance to the colors. You'll also notice that the colors that you are referring are used by Johnny Walker ... it's just the colors of their choice.
The label is just below what they like, what their designers to come with labels, and sometimes just pure coincidence. The fact that the colors of the different qualities of JW are significantly different from each other is going to allow the customer to know at a glance that they were seized.

It just is not so complicated or mysterious.

The color of the label you are talking about seems to be that used for Johnny Walker Scotch Whisky blended.

Its just a marketing strategy to enable the distinction between their various products.
Red is the least expensive theirs, black is better and the blue is really top shelf with a price to match.
The colors were probably chosen because at the time these labels were designed, the image of whiskey has been one of maturity, quality and virility. Labels with colorful floral motifs would not go well received by drinkers :-)

thats the Coler they came with them could go out with thoes Agent Coler soon but not now
