The article says

It is also the name of the typical color of the pigment, which is a bright but somewhat lighter and very slightly orange shade.

which makes very little sense to me. Any suggestions? --Phil | Talk 14:58, Apr 7, 2005 (UTC)

I guess it is missing the word 'red', as in;

It is also the name of the typical color of the pigment, which is a bright red, but somewhat lighter and very slightly orange shade.

On the other hand, I think we can probably write a better entry. -- Solipsist 19:25, 7 Apr 2005 (UTC)

[edit] Color codes

Where do the color codes come from? I haven't been able to find any reliable source on the Web. Yes, I found pages claiming that vermilion is such and such in RGB/CMYK/HSV, but no evidence to back that up.

[edit] Red or Orange?

Is vermilion a red pigment, or an orange one. All I know is that it is my most favorite color. When I was 5 people used to call me Orange. So I hope Vermilion belongs to the orange family. I've read on encarta that it is a red pigment.

Traditionally, in an artist's pallette, I think Vermilion has always been considered a red. But it is quite an orange red. Cadmium red is a cheaper stronger red used today, which would give you the wiggle room to call vermilion an 'orange-red used by purists'. -- Solipsist 19:01, 28 July 2005 (UTC)

[edit] Updated color codes

Vermilion
— Color coordinates —
Hex triplet		#E34234
RGBa	(r, g, b)	(227, 66, 52)
HSV	(h, s, v)	(5°, 77.1%, 89%)
a: Normalized to [0–255] (byte)

I've updated the color codes based on these actual spectral measurements of genuine Vermillion pigment: http://www.handprint.com/HP/WCL/huepurity.html The author is quite thourough, and his data can be trusted. I'll update a few other pigment pages with similar color codes. The color codes started with CIEL*a*b, and were converted to sRGB based on the 10 degree observer and D65 whitepoint assumptions, and are designed for a monitor gamma of 2.2. If you change the values, please have a source based on actual measurements. It would probably be appropriate to add a few additional colors as well, to indicate different hues of different types of vermillion (since it can vary so much from source to source), if anyone has some measurements of their own.
