HEX color to RGB

---

Hi guys, I have a variable filled with a HEX color (e.g. #FF0000). Is it possible to convert this to a RGB color? It doesnt matter how many variables will be used, like 255,0,0 to one variable or to 3 invidual variables (one for red, green and blue).

@gratizzz I think the easiest way for this is a litte helper script like this:

#!/bin/bash
hex=$1
printf "%d,%d,%d" 0x${hex:0:2},0x${hex:2:2},0x${hex:4:2}

you can use this script like ./HexToRgba.sh 48f442 which returns 72,244,66.

@thost96 working great! Maybe a newbe question but what is the best way to get the result in a pimatic variable?

@gratizzz try this code. Update info where needed;

#!/bin/sh

hex=`echo $1 | tr '[:lower:]' '[:upper:]'` 

a=`echo $hex | cut -c-2` 
b=`echo $hex | cut -c3-4` 
c=`echo $hex | cut -c5-6` 
r=`echo "ibase=16; $a" | bc`
g=`echo "ibase=16; $b" | bc` 
b=`echo "ibase=16; $c" | bc` 

#post to pimatic
#generate value to variable, seperated by a comma
value=$r','$g','$b
#pimatic username
user=yourusername
#pimatic password
password=yourpassword
#variable you want to change
variable=test
#pimatic ip address
pimaticip=192.168.0.0

#do the actual variable change through patching
curl -s -X PATCH --header "Content-Type:application/json" --data '{"type": "value", "valueOrExpression": "'$value'"}' --user "$user:$password" http://$pimaticip/api/variables/$variable > /dev/null

exit 0

Since the forum alters posted code, here is a pastebin link if copying this code doesnt work;

Use sameway as mentioned before.
