Tɛmplet:Element color

Template documentation[view] [edit] [history] [purge]

This template returns the element's legend color, to be used in HTML makeup:

{{Element color|f-block}} → #9bff99

Some color codes are designed as fontcolor.

Some return values are designed as full border settings:
{{Element color|Synthetic}} → 2px dotted #6e6e8e

Note: the true code returned is like: #ffc0c0; (# being "#"). This way, any HTML page will not use "#" to start a numbered list.
