To use a colour in a template or table you can use the hex triplet (e.g. #CD7F32 is bronze) or HTML color name (e.g. red).. Editors are encouraged to make use of tools, such as Color Brewer 2 to create Brewer palettes, listed at MOS:COLOR for color scheme selection used in graphical charts, maps, tables, and webpages with accessibility in mind for color-blind and visually impaired users.

Specifying a size does not just change the apparent image size using HTML; it actually generates a resized version of the image on the fly and links to it appropriately. This happens whether or not you specify the size in conjunction with "thumb". This means the server does all the work of changing the image size, not the web browser of the user.
In very brief summary, one hurdle that trips up many people when attempting to add an image to an infobox template is that most internally provide the wiki code that "wraps" the image. Accordingly, you do not usually add the brackets, number of pixels, and other code details you will learn about below, when placing an image in infoboxes ...
