htop.used = top.used-top.buffers-top.cached = free."-/+ buffers/cache".used
i.e. htop only shows application memory, ignoring cache and kernel buffers.

Try enabling display of kernel threads in htop. Or press T. It's one of two, I don't remember exactly.
About memory. htop only tells you the memory actually used by applications. If only F1 were pressed: green - used, blue - buffers, yellow - cache.
