Nice plants.
This is a more common scenario than most realize. Despite advances, camera processor and sensor technology still lacks ability to consistently differentiate some portions of the colour spectrum. Sometimes camera pics can be very deceiving...
...I have a lindleyanum var kaieturnum x pearcei var ecuadorense that looks predominantly green with flash but when shots are taken without a flash reds and browns are far more prevalent (as stripes and shading).
Regardless, your plants are beautiful.
