The rule of original Boulder Dash is: amoeba always goes dark green and slime goes dark blue. Since the c64 doesn't have the same char mode which can set a separate amoeba/slime color just by setting a char attribute, they decided to set the walls dark green with it in all amoeba caves in BD1. They used a brighter wall color in all other caves. The CPU time wasn't sufficient to write all the color RAM, so they abandoned that idea, too.
In BD2, they did a different approach to "solve" this. They invented the dirt mod, ie. they changed the amoeba/slime color to the main dirt color, and to make it more distinguishable, they swapped the dirt colors in all amoeba caves. The issue with that is they sacrificed dirt contrast to the boulders and titanium walls, which is why many fans didn't like that, but No One and Prof. Knibble obviously did, though. Even worse, Prof. Knibble forced the low contrast dirt for all caves in some games. I changed it back to the original dirt colors in my Deluxe Construction Kit since v2.6, and I also changed the amoeba graphics to the BD1 one and the slime graphics to the BD2 version at the same time, to give new games a more classic and more colorful appearance.
Also, to understand some limitations, another rule of original Boulder Dash was: no amoeba and slime in the same cave. This is because they share the same graphics, and it wasn't possible to give them different colors in the same cave. They even forced the official Construction Kit to only use one of them, eventhough the engine has no problem having both elements in the same caves. And infact, many caves made with hacked Construction Kits (or by exploiting glitches) did just that.

(main and three others tiles for dirt. in fact, every single tile could be have more than one usable graphics element with same functionality. especially dirt and walls)
That would require a massive engine reorganization. So it won't happen.
The closest to this is XDC's ability to have both dirt versions (original and swapped color version) in the same cave, to give it some diversity. That's about it. I ran out of tiles, so there will be no features requiring additional graphics.
Things on my todo list:
- Fix Crazy Light Tools for JiffyDOS.
- Finish XDC some day.
