Respect

[DarkByte]

How it's possible to make the respect color like in the image. For example if respect is 0 to be green, if it's decreasing to get to red and if increasing to go to blu and so..like in this spectrum below

You have to use statments and interpolateBetween.

Found this, but how to manage it an get it to a color?
 

local function wavelengthToRGBA(length) 
    local r, g, b, factor 
    if (length >= 380 and length < 440) then 
        r, g, b = -(length - 440)/(440 - 380), 0, 1 
    elseif (length < 489) then 
        r, g, b = 0, (length - 440)/(490 - 440), 1 
    elseif (length < 510) then 
        r, g, b = 0, 1, -(length - 510)/(510 - 490) 
    elseif (length < 580) then 
        r, g, b = (length - 510)/(580 - 510), 1, 0 
    elseif (length < 645) then 
        r, g, b = 1, -(length - 645)/(645 - 580), 0 
    elseif (length < 780) then 
        r, g, b = 1, 0, 0 
    else 
        r, g, b = 0, 0, 0 
    end 
    if (length >= 380 and length < 420) then 
        factor = 0.3 + 0.7*(length - 380)/(420 - 380) 
    elseif (length < 701) then 
        factor = 1 
    elseif (length < 780) then 
        factor = 0.3 + 0.7*(780 - length)/(780 - 700) 
    else 
        factor = 0 
    end 
    return r*255, g*255, b*255, factor*255 
end 

 

[Simple0x47]

function getColor( length )
  local rel = length / maxLength -- Define your own maxLength for having a decimal value
  local r, g, b
  if ( rel > 0.5 ) then
    local p = ( rel * 0.75 ) / 0.5
    r, g, b = interpolateBetween( 0, 255, 0, 0, 0, 255, p, "Linear" )
  else
    local p = ( rel * 0.25 ) / 0.5
    r, g, b = interpolateBetween( 255, 0, 0, 0, 255, 0, p, "Linear" )
  end
  return r, g, b
end

Not working.

Well, here you go, perhaps this does something of that sort.

but how to increase it like a gradient? to change the color step by step hope you understood me

Use interpolateBetween, you could try something yourself for a change.
