Is Black all colors or no colors?
Black would be no colours. the way we see things, is that light bounces off a surface, and into our eyes. The colour of the surface decides the colour of the light that is bounced into our eyes, and allows us to tell what colour it is. If there either isn't any light, or nothing that bounces in our direction, then we'll see the absence of light as black.
What is the difference between reagent blank and sample blank?
Reagent Blank : Take reagent and add deionised water (in place of sample to be tested). Now measure the OD at specific wavelength --> this OD is your reagent blank. Substract this OD from your test result (with sample) to avoid any false +ve effect due to colour of reagents itself.Sample Blank : Take sample and measure the OD without adding reagents --> this OD is your sample blank. Substract this OD from your test result to avoid any false +ve effect due to colour and turbidity of sample itself. As it is the fact that colour and turbidity of each sample would vary from one to another.So now it is clear that Reagent blank is used to avoid bias due to colour of reagents and Sample blank is used to avoid bias due to sample itself.

When a room is dark are the colors of everything still there?
In a dark room, colors are still present on objects, but they appear dark or black because there is not enough light to reflect off them and reach our eyes. Colors are a result of light interacting with objects, so without light, we cannot perceive the colors as we normally would.
