You can try using the quick timelapse feature. Change the config.py setting
motionQuickTLOn = True
Then you can adjust the time period that quick timelapse feature is run for using
motionQuickTLTimer = 10
It is the number of seconds that the quick timelapse runs for after motion is detected. Set this to the number of seconds.
The camera needs time to warm up and establish white balance. During the pi-camera initialization there is a sleep to allow camera to establish white balance. If a very short delay is specified the camera white balance will not be correct and images will not be consistent. The default is .5 seconds on line 364
def takeDayImage(filename):
# Take a Day image using exp=auto and awb=auto
with picamera.PiCamera() as camera:
camera.resolution = (imageWidth, imageHeight)
time.sleep(0.5) # sleep for a little while so camera can get adjustments
.5 seconds is about as short a warm up as reasonable and still get half decent image consistency. You will still find variations in white balance a this low level. BTW the default rpistill is 5 seconds.

Using raspistill you can do a timelapse sequence that only has one warm up but pi-timolo uses pi-camera python library and needs to switch between motion detection and taking images or video sequences. This means the camera needs to switch between these modes and warm up between. It would be possible to shell and run raspistill in a timelapse sequence
