Why does my phone camera show a purple/blue color effect in the center of flower photos?

When photographing a Lobelia flower with a Realme 5 phone camera, I see a purple/blue color shift that appears differently in the center of the image than around it. As I move the phone, the effect stays consistent rather than moving like a normal reflection or flare. What could cause this, and is it likely to be a camera setting or image-processing issue?

From a camera review:
The camera app offers AI scene recognition - you'll see a small icon when a scene is successfully recognized, and the software will tweak all settings accordingly. Food, snow, pets, sunsets, grass, among other scenes, are detected mostly correctly.
So this is possibly a case where the "mostly" in "mostly correctly' applies. The scene isn't recognized properly and the camera applies the wrong tweaks (for instance adding some red for better skin tones). What is the scene icon? Can you disable this (or use a different camera app)?

This is most likely caused by the phone camera’s automatic scene detection and image processing rather than by the lens itself.
The Realme camera app can recognize scenes and then adjust color and other settings automatically. If it misidentifies the subject, it may apply the wrong color tuning, which can create unnatural purple/blue shifts in parts of the image. Since the effect stays consistent as you move the phone, that points more toward software processing than a physical lens artifact.
Things to try:
- Check whether AI scene recognition is enabled.
- Turn off scene optimization/AI enhancement if possible.
- See what scene icon the camera shows when aiming at the flower.
- Try a different camera app to compare results.
If the color cast disappears with AI features off or in another app, that strongly confirms it’s a processing issue.
