The term blue generally describes colours perceived by humans observing light with a dominant wavelength that's between approximately ...
Hazels are plants of the genus Corylus of deciduous trees and large shrubs native to the temperate Northern Hemisphere. The genus is usually placed in the birch family Betulaceae, [2][3][4][5] though some botanists split the hazels (with the hornbeams and allied genera) into a separate family Corylaceae. [6][7] The fruit of the hazel is the ...
