What ever colour you perceive the piece of cake to be.
Essentially it's 'brightness' on the vertical scale and colour on the horizontal scale. The brightness can be expressed as luminosity, compared with our suns luminosity, or as absolute magnitude. The colour can also be expressed in terms of temperature, the colour shows what the temperature is. The colour can be categorised in to groups or spectral classes.
This area is called the retina. It consists of different sets of receptor cells that are specialized in their function to aid in the perception of light and colour.

certain types of color receptor cells, called cones.
The four main types of perceptual constancies are size constancy, shape constancy, brightness constancy, and color constancy. Size constancy refers to the perception of an object's size remaining the same despite changes in its distance from the observer. Shape constancy involves perceiving an object as maintaining its shape even when the viewing angle changes. Brightness constancy is the ability to perceive an object as maintaining a consistent level of brightness under different lighting conditions. Color constancy is the perception of an object's color remaining the same under varying lighting conditions.
Neither, most sea water is relatively colourless with the actual colour coming from a reflection of the sky.
Jesus was neither colour, but the colour of a Jew, which is generally light brown.
That is a matter of personal preference as some people would perceive certain colours differently and a colour that one person sees easily may not neccesarily be as easy to perceive for another person.
To Simply Convert The Shade To A More Lighter Tone.
Our eyes are our sense organ for detecting light. Their colour range is somewhat limited, being about one half of an octave. When we say we 'see something', or 'are looking at something', in reality we are merely receiving light from that object. We use separate sensors for brightness, and for colour. For colour we have three different colour sensors, which overlap in their bandwidth. Thus we perceive a broad range of colour. In dim light, our colour sensors are not active. Your eyes are an extension of your brain (whose whole surface is light sensitive), and each eye sends part of its output to both hemispheres of the brain. Many herbivores and carnivores have little use for colour, and waste no brain power on it. Some insects and butterflies can see a much wider range of colours that humans do.
