are there any studies on adverse effects of color doppler ultrasound in early pregnancy
No prenatal ultrasound studies since 1990, so no one can answer your question aside from saying, WE DONT KNOW.
Before 1990, the level of ultrasound was less than a third of what is used now, even without COLOR 3D. The correct answer to your question is WE DONT KNOW and there is no reason to believe it is safe, therefore no medical organization recommends routine prenatal ultrasound, yet nearly all doctors do.

Ultrasound devices generate energy and increase tissue temperature. Temperature increases have been proposed to be teratogenic. Increased heat to male gonads may cause subfertility/infertility. Doppler is specifically directed ultrasound energy.
It is not known whether ultrasound or doppler directly causes harm to embryo or fetus, but if that would be the case, than, it is quite logical to think that an embryo would be more affected by doppler, than fetus, since relatively more tissue than in a fetus would be subjected to ultrasound energy in case of an embryo scan.
"As low as reasonably achievable" or "As low as reasonably practicable" principles are always good.

Doppler US is contraindicated in women with elevated body temperature. Therefore, in those circumstances using Doppler US could be harmful to the fetus, so it should be not suggested.

Article Risks and Responsibilities arising from Prenatal Ultrasound
Article Prenatal ultrasound does not improve perinatal outcomes
but there is no clear evidence or paper on adverse effects of color doppler or spectral doppler on embryo or fetus--
There are no strictly defined limits for the use of Doppler ultrasound in the early pregnancy. However, there is an unequivocal demand for carefulness that is best expressed by the ALARA principle. The prudent use of Doppler takes into account benefits against the possible theoretical risks, rather than prohibiting clinically useful technology or applications.

to the very best of the currently available knowledge, this is safe, but obviously, it remains very difficult to proof absolute safety...
It is very good to see that many are aware of the potential dangers of ultrasound, maybe exaggerated, but I would like to remind that all of us have heard about ""sound waves initiating avalanches". Although the output of doppler seems to be low, we should remember that it is sometimes very much concentrated on a small area.
