That is interesting. Another interesting fact is that the most expensive pigment was made using the stone called lapis lazuli
Yeah I've never felt that way either. Neither did the ancient Egyptians when they used lapis lazuli for jewelry and the like.
I really love the color blue Nice to know that. Did you know that blue is a primary color in both painting and RGB colour model? Along with red and yellow, yes -- but blue is the best :) Agreed! It also lies just between the colors violet and green on the visible spectrum. There's nothing like a clear blue sky to cheer the soul Yup, it's weird to think that this is all due to the wavelength of the light, which would be between 450 and 495 nanometres for the color blue. I wonder why when people feel sad, that they say they feel 'blue'. I am not sure about that either, all I know is that blue is an important colour for decoration and arts since long ago But there's nothing about the color that makes me feel depressed.
The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in The Renaissance, to make the pigment ultramarine, the most expensive of all pigments.
