Change Icon color in a TimestampedGeoJson - python-3.x

Question

I am trying to make a map including popups with iframes markers with different colors and icons with the data included in a geojson . I have no problem with the popups, but I can't change the icon colors.
I have tried the following ways and other ones that I can't remember to introduce the color in 'properties' without any result:
{'type': 'Feature', 'properties': {'icon': {'color': 'red'},...}
{'type': 'Feature', 'properties': {'color': 'red',...}
{'type': 'Feature', 'properties': {'style': {'color': 'red'},...}
{'type': 'Feature', 'properties': {'icon': 'marker', 'color': 'red',...}
Here is my code:
import folium
from folium.plugins import TimestampedGeoJson
m=folium.Map(location=[46, 20.00],
zoom_start=7,
tiles="stamenterrain")
features = [{'type': 'Feature',
'properties': {'color': 'green',
'name': 'Photo 1',
'time': '2012-01-01',
'popup': "<iframe src=https://images.pexels.com/photos/96491/pexels-photo-96491.jpeg title='test' width='200' height='100'/>"},
'geometry': {'type': 'Point', 'coordinates': [19.295, 46.5116]}},
{'type': 'Feature',
'properties': {'color': 'red',
'name': 'Photo 2',
'time': '2012-04-01',
'popup': "<iframe src=https://images.pexels.com/photos/1145370/pexels-photo-1145370.jpeg title='test' width='200' height='100'/>"},
'geometry': {'type': 'Point', 'coordinates': [18.15291, 47.20544]}}]
TimestampedGeoJson(
{'type': 'FeatureCollection', 'features': features},
period='P3M',
duration='P2M',
auto_play=False,
add_last_point=True,
min_speed=0.5,
max_speed=2,
loop=False,
loop_button=True,
date_options='YYYY/MM/DD',
).add_to(m)
m
I expect to obtain a map with green and red colors, but markers are showed in blue.
If I use circle icon using 'properties': {'icon': 'circle', 'iconstyle': {'color': 'green'} the circles are created with teh correct color.

Answer 1

Replace color with iconColor like this:
'properties': {'icon': 'circle', 'iconstyle': {'iconColor': 'green'}
