This Sysex message is used to set a full RGB color of one of 64 pads on my Ableton Push

240 71 127 21 4 0 8 pad 0 rHi rLo gHi gLo bHi bLo 247


I already have a definition and a created a custom color table that matches the 0-127 midi velocities. But this is extremely limiting and I want to choose more colors. How can I set this up in my definition file so I can pick almost any color? Thanks.

We dont offer at the moment something to combine r,g,b inside a sysex, but you can try the following, just to see if its working that way...
<text sysex="F0477F15040008XX00000000000000F7">  
<digit name="LED_PAD_XX_RED" offset="9" nbbits="14" offsetbit="0" />
<digit name="LED_PAD_XX_GREEN" offset="11" nbbits="14" offsetbit="0" />
<digit name="LED_PAD_XX_BLUE" offset="13" nbbits="14" offsetbit="0" />
</text>

in the sysex you keep the bytes that dont change, and replace the ones that do with 00. Also replace XX with the Pad number.
(240 71 127 21 4 0 8 is F0 47 7F 15 04 00 08 in hexadecimal)
and then in mapping try to send constant values to see if its working.. so something like..
LED_PAD_XX_RED : constant 255
LED_PAD_XX_GREEN : constant 0
LED_PAD_XX_BLUE : constant 0
(should offer a red LED)
or
LED_PAD_XX_RED : constant 0
LED_PAD_XX_GREEN : constant 0
LED_PAD_XX_BLUE : constant 127
should offer a dark blue

In theory this should be also offered , but not sure if its working ...
<ledsysex value="F0477F15040008XX00000000000000F7"> 
<color name="LED_PAD_XX" bit="64" nbbits="42" bitspercolor="14" />
</ledsysex>

and then in mapping LED_PAD_XX : pad_color XX

This did work. I was able to set R G B separately 0-127 within the mapper. I will now try your second suggestion.

I do not think the Launchpad has the ability for full sysex rgb control like the Push. The launchpad does however have a very similar velocity color palette as the push as shown hhre:
