It happens due to redox reactions. Oxidized DCPIP is blue, while reduced DCPIP is colorless.
More specifically theres a Nitrogen atom joining two benzyl groups, that, when reduced, changes a double bond to a single bond, forcing several carbon bonds in the entire left benzyl ring to change conformation. This makes the molecule reflect light differently and accounts for the change in color perceived.

Can reagent bromthymol blue or phenolphthalein could be considered to be an acid indicator?
Bromthymol blue is yeloww in acidic solutions, penolphthalein is colorless.
Copper is added to a solution of nitric acid The solution becomes hot and changes from colorless to dark blue What is the best explanation for the change in temperature?
in study island, the answer is "The reaction between the copper and the nitric acid produces heat. It is exothermic."
What observations are seen between zinc and copper sulphate reaction?
Solution was blue initially, became light blue and then colorless. Zn is oxidized (Color changed to brown) and the reaction is exothermic.
What is a colorless hard mineral?
Diamonds are usually clear and they are hard. Zircon can also the colorless and is a hard mineral.
What happens if you mix bromphenol blue and NaOH?
Bromophenol blue pH indicator changes from yellow at pH 3.0 to blue at pH 4.6; it turns blue even in neutral water (pH=7) so when NaOH is added nothing really changes: blue = blue
What role DPIP plays photosynthesis?
In lab 4, DPIP is an electron acceptor that takes the place of NADP+. When DPIP is reduced, it changes from blue to colorless so you can see that the Calvin cycle is running.
What does DPIP stand for?
If you are referring to the "Plant Pigments and Photosynthesis" Lab Then, the DPIP is used to substitute NADP+. In photosynthesis, electrons are normally transferred to NADP+. However, DPIP will take its place in this experiment. DPIP is normally blue. When it is reduced, or gains electrons, it will turn colorless. DPIP is used to show that photosynthesis is taking place.
What is the effect of boiling the chloroplast on the subsequent?
Boiling chloroplasts prevents the DPIP from being reduced because the enzymes for photosynthesis are no longer present in the chloroplasts. DPIP is reduced from blue to colorless when light strikes the chloroplasts and the electrons are boosted to a higher energy level. Since photosynthesis cannot be performed by the denatured chloroplasts, the DPIP cannot be reduced.What_is_the_effect_of_boiling_chloroplasts_on_the_subsequent_reduction_of_DPIP
What is the function of DPIP in this experiment?
Is this an AP lab?The DPIP replaces NADP+.In photosynthesis, NADP is reduced to NADPH, but NADP is colorless.DPIP replaces the NADP. When DPIP is reduced, it changes from blue to clear. DPIP is used to show photosynthesis taking place.
Are boiled chloroplasts able to reduce DPIP?
Boiling chloroplasts prevents the DPIP from being reduced because the enzymes for photosynthesis are no longer present in the chloroplasts. DPIP is reduced from blue to colorless when light strikes the chloroplasts and the electrons are boosted to a higher energy level. Since photosynthesis cannot be performed by the denatured chloroplasts, the DPIP cannot be reduced.
Is helium blue or light blue?
Helium is colorless
Is oxygen blue?
No, oxygen is colorless
What is oxygen color?
Oxygen is colorless as a gas, but as a liquid it is pale blue.
Why is water not blue in a glass?
water in ocean or sea is colored blue because of the replection of the blue sky... water is colorless...
What colors can you get cremation diamonds in?
Red, Blue, Yellow, Green or colorless
What is color of the water?
The water looks colorless when in small quantities but it has actually a very slight blue hue to it. This can be tested with a glass of water and a filled bathtub: the former will appear colorless while the latter will be faint blue.
What colour is cyanide gas or vapour?
The Symbol for Cyanide is CN- The C is for Carbon, and the N for nitrogen.
