frida Kahlo : how to evaluate photos of paintings

None of the above PHOTOS taken from the internet is the original.
The photo on the left is not the original replica as visitors see in the exhibition: it is a cut image zoomed in, taken from the Museum website; the photo on the right is an extremely bad quality photo taken from Wikipedia.
Here a few suggestions on how to evaluate photos (from books or internet) of Frida Kahlo paintings:
1. Frida painted the objects she had at home: Maya or Aztec idols, furniture, pets, dresses and jewelry she had and wore;  
2. She painted objects in their real colors, for example: the blouse is white not grey, the monkey front is white not yellow, her hair band wool decoration is red not brown(see photos of Nickolas Muray), the butterflies on her hair are white not grey.
3. She painted mainly using pure colors: red is red not brown or pink, white is white not yellow or grey, yellow is yellow not greenish. 
4. She used few colors and she even described the meaning she gave to the colors.
5. She painted her face in natural colors, and never grey-yellowish. People who knew her described her skin tone as 'peach colored'.
We gladly share our know-how about Frida's paintings and the quality of printed images in books and internet with anyone who is interested.
