Problem
Red circles blend into red interface elements and fail to isolate the intended object.
Solution
Root Cause / Diagnostic:
Using standard red (#FF0000) annotation graphics against scenes or UIs that already contain red warning banners or warm elements eliminates chromatic contrast. The annotation camouflages into the background noise, failing its fundamental purpose of isolating detail.
Actionable Fix:
1. Calculate color contrast ratio and switch annotation stroke color to an opposing complementary hue (e.g., electric yellow #FFE600 or cyan #00E5FF against red backgrounds).
2. Add a dual-stroke layer style: 6 px vibrant interior stroke surrounded by a 3 px solid black or white outer stroke to guarantee separation across all backgrounds.
3. Verify annotation visibility by converting thumbnail preview to grayscale; ensure the outline maintains strong luminance contrast.
Pro Tip:
Dual-stroke annotations (e.g., yellow stroke with black outer outline) guarantee 100% edge readability against any background hue or luminance level.
