It's not earth and it's not properly balanced.
Yes, and look what happened to him.

Thank you for your explanation and the images!
I also think it is good to have an image of the sundial taken here on earth, so we know what the color targets look like:
Not necessarily, if you use a lossless file format like TIFF (which is hard to view online, only with special plug-ins) or the widely accepted (all browsers can show them) PNG files.

Then you must realize, files on the internet are not true color. If I scan in a light pattern, compress it, then upload it, there is data loss.
Right, and even the colours I see may not be (and most probably are not) the same colours you see, that is one of the things that change from person to person. Even one person can see in different ways with different eyes, my left eye sees things slighly red when compared with the right eye.
Light and Color will not be the same as it is in real life.
Refresh rate does not affect the colours, and if you want to guarantee image quality you should buy a colorimeter
Then you must account for every monitor on Earth is at a different brightness, contrast, resolution, refresh rate, color tones, and that as all monitors are aging, the quality drops. [I buy a new monitor every year to insure I see quality of pureness]
Seeing the exact differences is impossible, but a close approximation is enough for most people.
By the time you do all this, VISUALLY seeing the differences of Mars and Earth are impossible.
Two reasons why RAW images from digital cameras are so big do not apply to the rovers' (for exampl) photos:
Again: It is impossible without RAW data... all images on NASA's websites are not RAW data. A RAW image from most of their equipment would be in the hundreds of megabytes at minimum... most RAW images from digital single lens reflex cameras are 30-50 MB, in the lower-end professional equipment.
