Color (American English) or colour (Commonwealth English) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, etc. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space colors can be identified numerically by their coordinates.
Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance.
The science of color is sometimes called chromatics, colorimetry, or simply color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).
It's here I am today God gave and took away And left without a home for Dan O'Hara With these matches in my hand in the frost and snow I stand But here I am today your broken hearted
In the year of sixty four we had acres by the score The grandest land a man could pull a plough through But the landlord came you know and he laid our home to low And here I am today your broken-hearted
Cushla gra mo craoi won't you buy a box from me And have the prayers of Dan from Connemara. Sure I'll sell them cheap and low buy a box before you go from the broken-hearted farmer Dan O'Hara.
And for twenty years or more did misfortune cross our door My poor old wife and I were sadly parted We were scattered far and wide and our children starved and died But here I am today your broken-hearted
Cushla gra mo craoi won't you buy a box from me and have the prayers of Dan from Connemara. Sure I'll sell them cheap and low buy a box before you go from the broken-hearted farmer Dan O'Hara.
Tho' in frost and snow I stand beneath the shadow of God's hand It lies warm from the brow of Dan O'Hara And so soon with God above I will meet the ones I love And find the live I lost in Connemara
Cushla gra mo craoi won't you buy a box from me and have the prayers of Dan from Connemara. Sure I'll sell them cheap and low buy a box before you go from the broken-hearted farmer Dan O'Hara. 3x
