It all depends on the frequency of a wavelenght for example red is a low frequency and violet is a high frequency
there is no light to reflect off the object that you want to see
We see different colours because other colours are being absorbed.
easier for us to knowing different objects by their shapes, colours and textures
The cone-shaped cells in the eyes detect colours.
The cone-shaped cells in the eyes detect colours.
Different colours appear because it is the way the human eye perceives them. Colours have different wave lengths and human's eyes can see that which makes you see it as a colour. The thing that makes colours different is the size of the wavelength.
Where do you see the sand in different 5 colours
I use advanced technology to analyze and interpret visual information. This involves detecting various wavelengths of light that correspond to different colors, which allows me to perceive and understand objects that have color.
You can choose different colours to apply to objects and text.
You see different coloured objects by light. the light hits the object and reflects into your eyes.
Different species have different needs from their vision and may well see (Infra red/Ultraviolet etc?) and other totally different light frequencies from humans. They may also see some colours vividly and other colours as shadows, so their vision works differently from ours because different things are important to them. No doubt they will see whatever colours they need to see for their survival in their natural habitat.
We see objects in colour for two reasons. 1. The objects only reflects certain wavelengths (colours) and absorbs the rest this is due to the bonds in the object, bonds absorbed specific wavelengths of light. 2. When these reflected waves enter out eyes they hit cones at the back of our eye which translates these wave/photons of light into an image we can see.
