looks like massive use of red dye to me
over there they do not use Jalapeno’s either .
The pepper is called prik chee fah , or prik kee noo
probably they use both
Google : Thailand sauce sriracha
you can clearly SEE the differences , under Images
From someone who grows chile for a living if they are using a fresh red chile that is the correct color. The puree I have in my freezer is the same color and it is pure pureed fresh red chiles. They use color from red chile to make dyes.
