How can I select the original caption format?

I am creating subtitles with the program “Subtitle Edit” (https://github.com/SubtitleEdit/subtitleedit) and this generates a subtitle in SRT format. For example, I have added 2 texts with the different color style. One red and one blue:

File SRT:
1
00:00:05,871 --> 00:00:11,286
<font color="red"><b>Texto de color rojo </b></font>

2
00:00:15,383 --> 00:00:20,192
<font color="blue"><b>Texto de color azul </b></font>

If I add that caption to a entry in Kaltura it ignores the style of the SRT created:
