چکیده

این پژوهش عدم تطابق رنگ را در بن‌سازه‌های تجارت الکترونیک با استفاده از کارت رنگ استاندارد و شرایط مشاهده شبیه‌سازی‌شده روی دو نمایشگر مختلف بررسی می‌کند. تصاویر محصولات با یک دوربین گوشی هوشمند تحت نور استاندارد D65 ثبت گردیدند و سپس روی نمایشگرهای Samsung SyncMaster P20500 (نمایشگر مصرفی) و EIZO CG243W (نمایشگر حرفه‌ای) نمایش داده شدند. اختلاف رنگ بین رنگ واقعی نمونه‌ها و رنگ نمایش‌داده‌شده با طیف‌سنج اندازه‌گیری و بر اساس فرمول ΔE2000 گزارش شد. نتایج نشان داد که میانگین اختلاف رنگ می‌تواند تا ۸ واحد برسد. این مقدار به‌وضوح از آستانه ادراک انسانی فراتر است و ممکن است منجر به نارضایتی مشتری شود. حتی پس از حذف خطاهای ناشی از عکاسی، اختلاف رنگ در برخی رنگ‌ها به‌ویژه رنگ‌های اشباع و تیره همچنان قابل‌توجه باقی ماند. نمایشگر EIZO به‌دلیل واسنجی دقیق‌تر و گستره رنگی بیشتر، عملکرد بهتری از خود نشان داد.

چکیده [English]

This study investigates color inconsistency on e-commerce platforms using the ColorChecker SG chart and simulated viewing conditions across two distinct displays. Product images were captured with a smartphone camera under standardized D65 illumination and displayed on a consumer-grade Samsung SyncMaster P20500 monitor and a professional-grade EIZO CG243W monitor. Color differences between the physical reference samples and their on-screen representations were measured using a spectrophotometer and quantified using the CIEDE2000 (ΔE2000) formula. The results showed that the average color difference could reach up to 8 units. This value clearly exceeds the human perceptual threshold and may lead to customer dissatisfaction. Even after accounting for camera-related errors, significant discrepancies persisted, particularly for saturated and dark hues. The EIZO monitor demonstrated superior color reproduction due to its factory calibration, wider color gamut, and higher color fidelity.
