Dear Community,
I'm really silly but why Workings followed Code not


The Idea behind this Code is to Mixing both Colors:
Color1 '(12 12 12)
Color2 '(122 122 122)
Not when the Subroutine Painter is called
Which Should Paint a Rectangle Across the Screen
And in the Hights y yd

Dear Community I hope you can help me.
But it can been that this is Working, and Mistake
is anywhere Else in my Program.

P.S.: The Complete Program is attached. But in this Version the Canvas must Uniformy Colored, but the Program results in a Mixed Colored Image.

Hello

adapt does not work because:

• "l" is not defined. It is supposed to be l1
• The + operator is between its two operands instead to start its list

adapt is the identity function independently of l2 and m. It always returns its first operand l1.
Since
R => R*m - R*(m-1) = R
G => G*m - G*(m-1) = G
B => B*m - B*(m-1) = B
Note your inversion (- 1 m) meaning that it is not an addition but a subtraction.

Never use l1 or l2 because it is so clause of 11 or 12.
It is about color so call them color1 and color2.

Never use a parameter having only one letter such as m.
It is not about mathematics!

Always align parenthesis.
Always give an example with the expected result.


In the Script-Fu console:

The expected result will be:
(12.0 12.0 12.0)

Hey AlSchemist,
I have tested your Script and have found an Error which leads me to another Error.


I hope you can see that I must changed the Second Color1 to Color2.
This is in Because I need the Mixing between Color1 and Color2.
Then I have get another Error, When I give the Subroutine equal Lists all working.
But when I try to mix different Lists I got duplicated Values near the Right Result but computational Wrong.

So I now have tried to address Results which are Integer-Lists,

then It works perfectly

I think that I have understand the Mathematical Background, and them seams correct
but can Anybody find the Problem.
