Eugene,
Please check the preferences for HTML editor here : Window > Preferences > MyEclipse > Files and Editors > HTML > HTML Source > Syntax Coloring. You can change the ‘Attribute Values’ preference.
For JSP tags, change the preferences here : Window > Preferences > MyEclipse > Files and Editors > JSP > JSP Source > Syntax Coloring.
Please note that versions earlier than MyEclipse 2016 are no longer fully supported. It is recommended to upgrade to MyEclipse 2017, our latest release based on Eclipse Neon.
