object colour: magentaligh colour : green why is the light colour reflected black!!!????????object colour: yellow light colour: blue why is light colour reflected black???i dont understand!!!
Our eyes have receptors for red, blue and green. With these kinds of colour receptor we can sense millions of different colours. Subtractive colour theory has the primaries red, yellow and blue; secondaries colours green, purple and orange made by combining 2 primaries. However you are talking about shining a light and looking at what reflects back, so additive colour theory is more appropriate here. Additive colour primaries are red, green, blue (yes the same as the receptors in our eyes, not a coincidence); additive secondaries are yellow, cyan and magenta (same colours used as transparent inks in full colour printing, once again not a coincidence). Magenta is made by adding red light to blue light, note that green is missing. Therefore if you shine a magenta light onto a green coloured object, there is no colour of light that the object can reflect back, so it appears black.
RGB vs CMY The additive colour thought states that an merchandise reflects or transmits easy of right here colours by potential of including the two next to it (or leaving out the only that is lacking: purple - Y+M green - C+Y Blue - C+M while subtractive colour thought states that an merchandise absorbs right here colours and produces the only next to them: Cyan - purple Magenta - green Yellow - Blue Or by potential of subtracting those 2 colours from one yet another: Cyan - G-Y Magenta - B-Y or R-C (there are conflicting theories approximately this one for the reason that magenta is genuinely an imaginary colour) Yellow - G-C SO: a Yellow balloon is a balloon that reflects yellow easy. for the reason that there is yellow in green it is going to reflect that and look yellow in case you shine a magenta easy one it, magenta -green that's comparable to purple plus blue. for the reason that yellow is absorption of blue, purple would be contemplated: it is going to be purple
