Unfortunately, Old Glory Blue is closer to navy blue than to royal blue. Navy blue has its origins in indigo. The US flag was inspired from the flag of the British East India Company. This happened much before 1830-1837 when the term Royal blue is supposed to have come into existence. The term "Old Glory", however, was coined in 1830-1831, but the color was not changed.

Whatever may be the link between ultramarine and paintings of clothing, one has to accept the fact that ultramarine is not a dye, while indigo is. So one may want to dye clothing with indigo to look like lapis lazuli, but that isn't going to happen. So traditional fabric colors, and their names, will always be some shade of indigo, or maybe even indigo and alizarin.

PS: all this is only valid for the actual flag. The blue of the flag will of course look different depending on the lighting around it, as will a painting of the flag.

Re: Royal Blue

Somewhere, many many years ago, I read an article that said the color blue royalty wears is slightly on the purple side. As a result of that I've always imagined it was more a very rich ultramarine or lapis color.

Re: Royal Blue

This is what Kremer pigments says:

Phthalo Blue, Royal Blue
Heliogen Blue
Chemical description Copper phthalocyanine. Pigment Blue 15:3, C.I. 74160

The Pigment of Art Database uses the term Royal Blue for phthalo as well as cobalt blue, and then there is the Royal Smalt which says it is superior fine grade.

Re: Royal Blue

After reading through this interesting thread, I'm beginning to develop the impression that the color-concept for "royal blue" is so wide-ranging (note how many people on this thread put in their two cents!) that it can't really be adequately defined. I put the terminology into the same category as "fire engine red" or "Van Dyck Brown". Consequently, if I hear of an instructor suggesting I go get a tube of "royal blue", I'll probably haughtily sniff in derision at the lack of pigment sophistication behind the suggestion. A quick look at this pigment database http://www.artiscreation.com/blue.html indicates that the word "royal" appears on paints that contain at least five different blue pigments.

Re: Royal Blue

All of which simply proves, once again, that manufacturers use paint names in so many different ways as to make the names virtually meaningless.

For example, look at the entire 200+ line of paints from D. Smith. The names are wonderful marketing terms...the best in the paint business!

It's the pigments and pigment index which defines the paint, not the name.

But it's so much more convenient and appealing to just use a paint name...especially something exotic...like..."Royal"!

I'm waiting for someone to bring out a Royal Sap Green...

Sling paint,
Virgil

Not necessarily. PBr7 or PR101 or PR122 or PV19 all come to mind. Depending on how they've all been manufactured, different colours result from the process. It's important to cite the Colour name, index and brand to provide actual identification of a colour.

For example, Da Vinci's PR101 Venetian Red is a different hue than Winsor & Newton's PR101 Burnt Sienna.

Re: Royal Blue

Yes, Char, this is a good example of where more than one colt is manufactured from tha same pigment. And to make things just a bit more confusing, even paints with the same name and pigment index will appear somewhat different from different manufacturers!

Sling paint, Virgil

Here we go again. We've said that. MAF 370. It is the one that was lost when the maps changed and so it fall from the edge of the world where the dragons lie.

And btw.. I'm not your dear.
"Dear" is an expression that is used to persons that are familiar to you.
It is though a different thing to be familiar from acquiring familiarity. In that second case it sounds simply rude.

Agreed. It's patronizing, condescending, and I took it as sexist when used in a response to one of my posts in another thread. It is an inappropriate way to address people you don't know in a forum like this.
