Hello,

We recently replaced the hires camera ([Link](https://www.modalai.com/collections/accessories/products/msu-m0025-2)) connected to our VOXL2 board with a new camera that has 146 degree of FOV ([Link](https://www.modalai.com/collections/accessories/products/msu-00024-1?variant=44804551049520)). After the replacement, the camera server is functioning correctly, and the video output is fine. However, as you can see in Photo 1, the colors appear overall reddish. Photo 2 shows the result captured by the previous hires camera. We have purchased two cameras, and both exhibit the same color issue.

We are seeking guidance on how to resolve this color issue. Has anyone encountered a similar problem before? Do you have any suggestions or troubleshooting steps we could try to rectify this? Any help would be greatly appreciated.

Thank you in advance for your assistance.

When I switch to the M0025 camera, everything is fine. However, when I connect the M0024 camera, I encounter the this problem as described in my previous post. Could you please provide some guidances into why this issue might be occurring?

That's the tuning we have on the wide FOV lens for IMX214. We will investigate in the next few months to see if we can improve.

@Chad-Sweet Is there any way I can tune it myself? If so, please provide a guide.

@Chad-Sweet I changed some parameters in `voxl-camera-server.conf`. I replaced "ae_mode" from `lsp` to modal`. After changing it, I typed `voxl-send-command` to calibrate color. That command didn't work and exposure and gain didn't changed. Do you have any advice? Or Is there a camera driver to tune color?
