It is Opaque letting no light through.
No, any color may be opaque, even white. Opaque is simply the quality of not being transparent or translucent.
The answer to the riddle "What is black when it's clean and white when it's dirty?" is a chalkboard. When a chalkboard is clean, it appears black; however, when you write on it with white chalk, it becomes "dirty" and takes on a white appearance.
A transparent material one that allows light to pass through with little absorption or distortion. If there is distortion, one might use the term translucent instead of transparent. More technically, one refers to a materials as being able to transmit light for a particular range of color as being transparent in that color range. Water is transparent for light in the range that the human eye can detect, but just outside that range, it becomes highly absorptive and would, if we could see, appear black. This is generally true for glass, air, salt and other materials which we would nominally characterize as transparent. Objects that absorb in a portion of the visible spectrum will transmit light that is a color formed from the portion of the spectrum that is not absorbed (portion that is transarent).
transparent objects are transparent because your eyes tells you so. In reality, every body sees every colour differently as our eye cells are not the same. So, in answer to the question, yes, but you cannot see it.
the wave length of light that is absorbed by the object determines color--White refects all eye perceptible colors where as black absorbes The colour of an opaque object is determined by the wavelength of the visible spectrum that it reflects. Light is made up of 7 colours, each having a specific wavelength range. Consider an object which appears green to the eye. Actually the object is not green in colour, it only reflects the waves pertaining to green wavelength range. All other wavelength are either transmitted or absorbed. The reflected wave reaches our retina and is perceived as that colour.
One would describe a high-quality black diamond as translucent, not as transparent.
No, any color may be opaque, even white. Opaque is simply the quality of not being transparent or translucent.
Roller blinds can be either transparent, translucent, or opaque, depending on the material used. Transparent roller blinds allow light to pass through while providing some privacy, translucent roller blinds filter light and offer moderate privacy, and opaque roller blinds block light completely and provide maximum privacy.

A chalkboard is black when clean and dirty when written on with white chalk.

I think you can just wipe it with a baby wipe
