Hi all

I am converting data from YCbCr to RGB Using

R= (Y + (1.4075 * (Cr - 127))) ))
G=( (Y1 - (0.3455 * (Cb - 127) - (0.7169 * (Cr - 127)))) )
B=( (Y1 + (1.7790 * (Cb - 127))) )

But not getting the right colors like Yellow colors look very near to
safron.

Please suggest some idea to recover from this.
