Found something that does not work correctly? Please include your browser name and version, operating system, device type, and a description of what you expected versus what happened. Screenshots are always appreciated.

Feature Requests

Want to see a new color format, additional palette types, a contrast checker, or other tools? Tell us what you need and how you would use it. Real usage examples help us prioritize development.

For collaboration proposals, educational partnerships, press inquiries, or content syndication requests, please use the same email address with a clear subject line.

What Happens When You Email Us

When you send an email to our contact address, here is what you can expect. First, you will receive an automated confirmation that your message has reached our inbox. This helps you know your message was not lost to a spam filter or other technical issue. Next, our team reviews every incoming message. Simple questions and bug reports typically receive responses within one to two business days. Complex feature requests, research inquiries, and collaboration proposals may take longer as we often need to discuss them internally before responding. We do not share your email or any information from your message with third parties, and we never add correspondents to marketing lists.

Response Time Expectations

We respond to most messages within one to two business days. Messages received on weekends or holidays are read on the next business day. Research inquiries, complex technical questions, and collaboration proposals sometimes require longer response times as we may need to consult with team members or prepare detailed information. If you do not receive a response within five business days, please resend your message - occasionally messages are filtered incorrectly by email providers.
