MSI B450 Tomahawk Max wrong color

[ceronem]

Hi guys, thanks for this utility, on my motherboard MSI B450 Tomahawk Max it doesn't work well.
I'm trying the demo commands:
sudo ./target/release/msi-rgb 00000000 FFFFFFFF 00000000 # for green
and it give me color pusling from blue to violet

this:
sudo ./target/release/msi-rgb FFFFFFFF 00000000 FFFFFFF
give me color pulsing from violet to green

and this:
sudo ./target/release/msi-rgb FFFFFFFF 00000000 00000000 -ib
give me color pulsing from green to yellow
