10 Common Mistakes on Artists’ Websites
1 - Backgrounds
Don’t use any background image, texture or color that is busier, brighter or more colorful than your art.
2 - Navigation Buttons
Avoid buttons, especially ones that look like gelcaps. Use text, not graphics for navigation links.
3 - Hi-res to Lo-res
The web is low-res. Adjust image brightness/contrast after reducing the size for web display.
4 - Moody = MuddyContrast rules on the web. Putting dark images on a dark background is like hanging your painting in a poorly lit bar.
5 - Mac v PC
Love your Mac but review your web pages on a PC since that’s what most of your visitors will using. Text doesn’t always appear as designed.
6 - Say No To Scroll
Design for a screen resolution of 800x600 or expect a lot of people to miss what’s on the right side.
7 - Words Matter - A Lot! Do not use: Small fonts.
You’ll insult everyone over 40.
8 - Do not use: Long lines of text.
Use columns instead.
9 - Do not use: Underlines.Used exclusively for hyperlinks.
10 - Do not use: Text in muted colors.
Strong contrast between text and background is a must. Practical (readable) should win over pretty.
