Table 3. Colorimetric Data and Shielding Behavior (Transmittance % at 275, 300, 365, and 550 nm) of Fish Gelatin–CDs Films at Different % w/w of CDs^a.

								transmittance (%)
CDs %	L*	a*	b*	ΔE	YI	WI	opacity	275 nm	300 nm	365 nm	550 nm
0	98.56	–0.12	0.49	0.89	0.74	98.47	1.3	60.6	81.9	86.4	88.6
1	96.77	–0.58	6.47	7.01	9.95	92.74	1.4	42.8	73.9	82.1	87.5
3	88.75	0.04	25.4	27.55	42.60	72.22	1.5	33.6	65.3	76.7	84.8
5	88.86	–0.07	30.34	32.12	50.80	67.68	1.6	28.9	50.7	70.6	84.4

The results were expressed as L* (lightness), a* (redness/greeness), and b*(yellowness/blueness). The total color difference (ΔE), yellow index (YI), and white index (WI) were calculated using eqs 4, 5, and 6.
