Yellow light in evening setting

Hi

Hope anyone can help me.

I have set up my smartthings with hue bridge and bulbs.

I have a set up our kitchen with 4 spots and 6 bulbs to turn off the light based on movement in 3 different settings during the day.

Everything works fine except the thing (7pm to 5am) when it turns on some of the bulbs are more yellow than when turning on in the rest of the day.

It is set to 100% but more yellow… Why?? it has the same setting as the other two periods of the day, where the light I more bright???
