Which colour of light is diffracted most through diffractional grating?

the condition for a maximum is ;

dsinθ=nλ

let d and n be constant then θ (angle) increases as λ(wavelength) increases. So the θ will be the greatest for the highest value of λ ..........that implies the frequency is lowest.
So I think light of lower frequency are diffracted much ....Am I right?

For a given order of diffraction (n), that is true.
