Brief Answer:
Don't worry, it's normal

Detailed Answer:
Hi

Thanks for asking on Ask A Doctor platform

I have gone through the query and do understand your concern.
In early infancy there can be change in frequency, consistency or color of stool.
I won't get worried if baby is accepting feeds well, passing urine, active, playful and if stool is not mixed with blood, too frequent or watery.
I would like to know if there is any recent change in feed (change in formula feed, addition of formula feed with breast feed).
Recent change in feed or mother's diet may also lead to change in color of stool.
Most of the time the stool pattern gets normal within 3-4 days. In some cases green stool may be followed stool.
I would like to give some probiotics like lactobacillus or saccharomyces for 3-5 days as it helps in maintaining healthy gut flora.
Observe for any further change in stool pattern or any abnormal symptoms and if you notice any please consult your pediatrician.

I hope this helps.
Please let me know if you have any more questions.
Regards
