Frequently Asked Questions
What are design marketing tools?
Design marketing tools are online utilities that help prepare creative assets, campaign links, prompts, color systems, web styles, QR codes, and proportional dimensions. They support production tasks, but they do not replace strategy, accessibility review, rights checks, testing, or final design decisions.
How should I create a trackable QR-code campaign?
First use the UTM Builder to create a campaign-tagged URL. Then paste that link into the Smart QR Code Generator. Test the destination and scan the final QR code on multiple devices before publishing or printing it.
Do the generated QR codes include analytics?
No. The QR generator creates static QR codes. To measure visits, create a tagged campaign URL first and use that URL inside the QR code.
Which color tool should I use?
Use the Random Color Generator for one starting color, the Color Palette Generator for coordinated colors, and the CSS Gradient Generator for a progressive color treatment.
Are generated colors automatically accessible?
No. A visually attractive color combination may still have weak contrast. Test the actual foreground and background combination in context before publishing.
What is the difference between a CSS gradient and a color palette?
A palette is a reusable collection of colors. A gradient is a transition between two or more colors applied to a specific element. Choose the palette first, then build gradients from approved colors.
Does the Aspect Ratio Calculator resize an image file?
No. The Aspect Ratio Calculator calculates a ratio or matching width and height. Use the Image Resizer & Converter to apply those dimensions to an image file.
Can the AI Prompt Generator guarantee accurate or original results?
No. The AI Prompt Generator helps structure an instruction, but the receiving AI system can still produce inaccurate, generic, inconsistent, copyrighted, trademarked, or unsuitable material. Review every output before use.
