Disclaimer: 

It is important to note that the colors and quality of the artwork may vary due to your monitor settings, because all manufacturers have different default color calibration settings for most consumer monitor, they will all have a slightly different color output if you put one monitor next to another. Unless your monitor is professionally calibrated as those are used in the professional imagining industries (photographers, filmmakers), a very slight color variation maybe expected, also due to different kinds of lighting depending on where and how the artwork is being displayed under different lighting circumstances.  For best result, it is recommended to use good lighting.
