Deconz hue bulb change color from startup only brightness with transition

Hello,
i have a problem. If the bulb is set to 5000 kelvin and its turned off and i switch it on with 3000 kelvin and a transition of 10sec. the color changes slowly to 3000 within 10sec.
Is it passable to start with 3000 kelvin and it only changes the brightness?
