In the bottom section of the Zaikhya Syandana, the warframe's energy color is overriding the syandana's energy color. Right now, I have my syandana energy color set to Cyan, and it looks correct in the first photo because I set the energy color of the warframe to Default (no selected color). Black also works. But if I set my warframe energy color to any other color (for example pink or yellow), then the bottom part of the syandana loses its color.
Here I still have the syandana energy color set to Cyan, but I've changed my warframe's energy color from Default to White. Notice how the syandana has lost it's cyan energy color in this location.
