These settings were available in release 3.6.4 for the Ecliplse M4.
They were very usefull to set a different background color for java code within a JSP. You could distinguish between Java code and HTML code in a very convenient way.
I think it would be a very valuable feature for future releases of MyEclipse if it would be possible to set different background colors for Java and HTML code, as it used to be possible in 3.6.4!
