❓ FAQ
How accurate is the simulation?
Based on Brettel-Vienot-Mollon model. Good approximation but individual variation exists. For reference only.
Can I check website accessibility?
Yes. Upload webpage screenshots and switch modes to check contrast.
Are images uploaded?
No. All processing is local. Images never leave your device.
How do I use the results?
如果Simulated View中的颜色区分不清，建议在设计中使用除颜色外的Other视觉线索（纹理、标签、形状等）。
