Your flow could do with some debug nodes in which would help you to see what is happening.

When you click on a button, you either get a message with color1 OR color2. Your template has no memory of the previous messages which is why one changes colour and the other goes black.

One solution would be to save the colour in each side to the context store. Then when a button is pressed you get the other colour setting from the context. See https://nodered.org/docs/writing-functions#storing-data on how to store data.

Thank you very mutxh !
I still have some problem with the style

This is not working , how should i do it ?

.svg_1 {
stroke: none;
fill : {{global.get("color1")}};

}
.svg_2{
stroke: none;
fill : {{global.get("color2")}};

}

and the svg code :

 <rect  id="svg_1" height="127" width="147" y="33.4375" x="27.5" stroke-width="1.5" stroke="#000" />
  <rect  id="svg_2" height="152" width="191" y="210.4375" x="330.5" stroke-width="1.5" stroke="#000"   />

I wouldn't even try to do it that way.

Use the function nodes you already have to set the value it has and to get the value it doesn't have.

I tried it different ways, but not of them was good. Could you or someone help me out with some code ?

In your first function

msg.color1 = (msg.payload === "on")?"red":"lime";
msg.textColor = "white";
msg.ID1 = "svg_1";
msg.nameLabel ="Text w LED";
global.set("color1",msg.color1)
msg.color2  = context.get('color2')||"black";
return msg;

and something similar in your second function...
