RGB to XYZ and LAB colours conversion

I'm having problems converting colours from RGB to LAB space It should be straight forward using the formulas from here, only I'm getting back the wrong values RGB = 56,79,132 X = 8.592 - Y = 8.099 - Z = 22.940 and CIE-L*ab as - L* 34.188 - a* 8.072 - b* -32.478 This is my code; but I can't see where I'm going wrong. It maybe due to floating points like this fella before me. Thank you. ``` // user colour var Red = 56; var Green = 79; var Blue = 132; // user colour converted to XYZ space XYZ = RGBtoXYZ(Red,Green,Blue) var colX = XYZ[0]; var colY = XYZ[1]; var colZ = XYZ[2]; // alert(XYZ) LAB = XYZtoLAB(colX, colY, colZ) alert(LAB) function RGBtoXYZ(R, G, B) { var_R = parseFloat( R / 255 ) //R from 0 to 255 var_G = parseFloat( G / 255 ) //G from 0 to 255 var_B = parseFloat( B / 255 ) //B from 0 to 255 if ( var_R > 0.04045 ) var_R = ( ( var_R + 0.055 ) / 1.055 ) ^ 2.4 else var_R = var_R / 12.92 if ( var_G > 0.04045 ) var_G = ( ( var_G + 0.055 ) / 1.055 ) ^ 2.4 else var_G = var_G / 12.92 if ( var_B > 0.04045 ) var_B = ( ( var_B + 0.055 ) / 1.055 ) ^ 2.4 else var_B = var_B / 12.92 var_R = var_R * 100 var_G = var_G * 100 var_B = var_B * 100 //Observer. = 2°, Illuminant = D65 X = var_R * 0.4124 + var_G * 0.3576 + var_B * 0.1805 Y = var_R * 0.2126 + var_G * 0.7152 + var_B * 0.0722 Z = var_R * 0.0193 + var_G * 0.1192 + var_B * 0.9505 return [X, Y, Z] } function XYZtoLAB(x, y, z) { var ref_X = 95.047; var ref_Y = 100.000; var ref_Z = 108.883; var_X = x / ref_X //ref_X = 95.047 Observer= 2°, Illuminant= D65 var_Y = y / ref_Y //ref_Y = 100.000 var_Z = z / ref_Z //ref_Z = 108.883 if ( var_X > 0.008856 ) var_X = var_X ^ ( 1/3 ) else var_X = ( 7.787 * var_X ) + ( 16 / 116 ) if ( var_Y > 0.008856 ) var_Y = var_Y ^ ( 1/3 ) else var_Y = ( 7.787 * var_Y ) + ( 16 / 116 ) if ( var_Z > 0.008856 ) var_Z = var_Z ^ ( 1/3 ) else var_Z = ( 7.787 * var_Z ) + ( 16 / 116 ) CIE_L = ( 116 * var_Y ) - 16 CIE_a = 500 * ( var_X - var_Y ) CIE_b = 200 * ( var_Y - var_Z ) return [CIE_L, CIE_a, CIE_b] } ```
