I have been trying to do something like this in Lyx.
As you can see is a very simple style that I been trying to reproduce but without any success. I know there are to many questions related to this but I tried some of the answers but nothing seems to work. I also wanna know if there is a color package with a color like the one that I show in the image, I remembered reading something like this in another question that I can no find. I used the
xcolor package but when I tried to generate the PDF, there was always an error except when I used the "basic" colors.
Thanks a lot
