They are in RPG (off-line)
Green and yellow are in witch shop nearby smith (1,-1).
And for red mixture is needed to go to blitzbee island (-1, -3).
But it is very dangerous (almost deadly) until you are on level at least 50. But higher level is better.
To get there, it is needed to go through map of
southern port town,
leave this map in right bottom corner,
by map's left edge go to the south (follow shore of sea)
in next map go to the left and down - to find path, that will lead you to place where you can hihre a boat to blitzbee island
And it is really needed to have boosted walk speed - and don't try to fight any enemy. Just ignore them.
And of course, you need some planks and about 550 000 gold (500 000 for getting to blitzbee island - and 50 000 to get back)
