Abstract	We show that adding the intrinsic color excess ΔE $_{B-V}$ of a star to the interstellar E $_{B-V}$ can significantly change the estimate of its distance r. When ΔE $_{B-V}$ changes from $$0\mathop .\limits^m 0$$ to $$0\mathop .\limits^m 5$$ , the relative error δ in the estimated distance rapidly increases to 99.5%. For $$\Delta E_{B - V} > 0\mathop .\limits^m 5$$ , r cannot be determined from the distance modulus. The error δ depends neither on absolute magnitude M $_{V}$, nor on apparent magnitude m $_{V}$, nor on interstellar extinction but depends only on the star’s intrinsic reddening ΔE $_{ B−V }$. We provide quantitative estimates of the intrinsic reddening in stars. The mean values of $$\overline {\Delta E_{B - V} } $$ for B0 stars in open clusters and associations are $$0\mathop .\limits^m 2$$ and $$0\mathop .\limits^m 35$$ , respectively; $$\overline {\Delta E_{B - V} } $$ for Be stars is $$0\mathop .\limits^m 1 - 0\mathop .\limits^m 2$$ ; the effect of cooler companions on the color indices of OB stars can vary. The individual values of ΔE $_{B-V}$ for separate OB stars exceed $$0\mathop .\limits^m 5$$ and reach $$0\mathop .\limits^m 6 - 0\mathop .\limits^m 7$$ . We show that the intrinsic reddening of cluster stars produced by circumstellar gas-dust envelopes can be separated from the interstellar reddening even for the same extinction law.
