The electronic color code is used to indicate the values or ratings

There is no hex color code for a transparent or colorless color because there is no such color as transparent. Transparent is whatever color the backdrop is. Thus, there is an almost indefinite number of colors that could be considered feasibly transparent... but are not transparent. In other words, there needs to be a "transparent" option to switch any electronic color code setting to transparent.
