+Blending Dynamic Colors Tmux Powerline Segments
+===============================================
 
+The -l and -r options when used in conjunction with a recent version of Tmux Powerline
+that has the ability to selectively disable spacing and separators between segments allow
+for seamless blending of tmux-mem-cpu-load output with other adjacent segments.  The end
+result is dynamic changing of appropriate foreground and background colors as the start
+and end of the tmux-mem-cpu-load output string that is aggregated with other Tmux
+Powerline output to produce a more polished status line in Tmux.
+
+Segment Adjaceny before this feature:
+
+.. image:: seg-adj1.png
+
+Segment Adjaceny after this feature:
+
+.. image:: seg-adj2.png
+
+Note that the values for the -l and -r options  will be the standard Tmux integer color
+values.  They set the appropriate background and foreground colors used for the separator
+character when used with the poweline-left or powerline-right options so it is easy to
+match coloring to adjacent segments.  An example from the segment script that calls
+tmux-mem-cpu-load is as follows::
+
+  tmux-mem-cpu-load -q -v -l 52 -r 33
+
+This combines with theme options available to tmux-powerline, such as the following::
+
+  "disk_usage_cust 52 123 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 52 123 right_disable" \
+  "tmux_mem_cpu_load_cust 52 234 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 52 234 both_disable separator_disable" \
+  "batt_cust 33 154 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 16 33 N separator_disable" \
