tisztaság képlete excitation purity $$p_{e}={\sqrt {\frac {\left(x-x_{n}\right)^{2}+\left(y-y_{n}\right)^{2}}{\left(x_{I}-x_{n}\right)^{2}+\left(y_{I}-y_{n}\right)^{2}}}}$$

Telítettség

$R'=R/255$, $G'=G/255$, $B'=B/255$

$Cmin=min(R',G',B')$, $Cmax=max(R',G',B')$ (Value), $Terj=Cmax-Cmin$, $L=(Cmax+Cmin)/2$ (Lightness), $I=(R'+G'+B')/3$ (Intensitas)

$S_{L}=(Cmax-Cmin)/(1-abs(2.L-1))$ Saturation (Lightness),
$S_{V}=Terj/Cmax={\frac {Cmax-Cmin}{Cmax}}$ Saturation (Value)

$S_{I}=1-{\frac {Cmin}{I}}$ Saturation (Intensitas)

$Y(1-y\epsilon _{w})$ $100(y.\epsilon _{\lambda }-y_{\lambda }\epsilon _{\lambda })$

$Y_{\lambda }(1-y\epsilon _{w})$

$100(y.\epsilon _{\lambda }-y_{\lambda }\epsilon _{\lambda })+Y_{\lambda }(1-y\epsilon _{w})$
