The copper compound azurite is the oldest and most widespread source of blue pigments. In modern times, both cobalt and Prussian blue – one of the first synthetic pigments – have been in great demand by painters. Like purple, many organic sources of blue pigment used for making dyes are extremely rare and have been highly valued throughout history; thus the association with royalty or divinity. Tekhelet was a blue dye prized by ancient Israelites for ceremonial uses, and although its source has been lost over time it is believed to have been a specially prepared formula derived from a cuttlefish.

Blue is the color of the deepest things we know, the sea and the sky, so it has come to represent truth and wisdom. Blue tones have the most soothing effect, which may be why it is the most common favorite color. Because it is calm and clean it is a popular color in professional design.

There are almost no drawbacks to applying blue in artwork, as long as you know what you want to convey. It’s hard to overuse this color, but be selective of which tones you use to avoid a washed-out or dismal look, as some can appear gloomy – or “blue.” It contrasts well with orange and warm or golden browns.

Announcing the launch of my new Public Domain Photo blog!

My album of completely free stock photos is now live! The collection consists entirely of nature photos, i.e. landscapes. flowers, trees, insects, and wildlife (still in progress). All of the photos I’ve taken myself and released into the public domain. Browse through the easy-to-use gallery for your enjoyment or to find just the right photo for your next art project.

Public domain means they’re totally free for commercial and non-commercial purposes. You are free to copy, modify, or adapt these photos for web design, blogs, desktops, reference pictures, cards, paintings, sketches – whatever you like – no strings attached.

The only restriction is that you must pass along the favor – you may not restrict others from using the same free image by selling the original file, or by placing your copyright on the original. You don’t have to give source credit when using any of my photos – but a return link or feedback is always nice!

Let me point out that this is still a work in progress. I’m just starting out so the collection is rather small, but is expanding quickly, so be sure to add it to favorites and check back often. And by all means, share it with a friend! As always if you have any questions or comments, feel free to drop me a line.
