You're probably thinking of a filter, lens or gel. All of these can be used to unify the color of light which passes through them, allowing certain frequencies (or colors) through while blocking others as they are emitted from the source (ie a bulb) or before being picked up (like by a camera lense)
Answer
I believe the answer is Filter.
its called a filter.
a filter
the color of the light it reflects and absorbs. If the object reflects red and absorbs all other colors, the object will appear red.
this substance absorbs all colors of light except
Black is the color that absorbs the most light (that is why it is black -- because all colors of light are absorbed and so none are reflected back to your eye, making it look black). White reflects all colors of light, and so absorbs the least amount of light. White looks white, because all the colors combined make white.
Chlorophyll most heavily absorbs the blue and red spectrum.
A red book reflects red and absorbs all other colors. Hence the perceived redness of the book.
stained glass
since white ligth actually contains all colors of light, the transparent material only lets its color of light through. ie: blue filter allows blue light in
it reflects
reflection
the filter transmits red light and absorbs other colors.
True black absorbs all colors.
transparent colours are colors tht are very light such AZ pink and white :)
how are absorbs and colors related
its quite simple - if you like science. the crystal absorbs colors and reflects those in which itdoesn't need e.g. all since it is transparent - which is why it reflects different colors every time the light catches it.
It is because that is what transparent means!
Colors have different wavelengths that allows one's eyes to differeniate them. The colors seen on the ball are the colors the ball reflects. The ball absorbs all the other colors. Note that the color white is what your eyes see when all colors of the visible spectrum are being reflected at the same time.
No, the red absorbs all the colors in the light exceptred.
