If a result seems wrong

Include the foreground #RRGGBB, background #RRGGBB and opacity exactly as entered. Say whether the issue concerns the exact fraction, decimal display, rounded hex, copy action or local report. A value from the worked examples makes a useful comparison. Please describe the expected result and the method used to obtain it.

Check the model first

Alphaflat deliberately computes in encoded sRGB, with an opaque background and half-up 8-bit export. A linear-light calculation, an editor using a different working space or a browser's sampled pixels can disagree without showing an arithmetic error in this model. The guide explains these limits and the examples expose the channel steps.

Keep the message nonsensitive
