This dataset contains:
The raw data of Figure 3, 4, 5, 6 and 7.
The dataset training and test neural network.
The original image of optical photography.
The original images of SEM images. 

The figures are as follows:

Figure 3:
The dataset distribution and cGAN training loss curves.
(a–c) The thickness histograms of the entire dataset. (d) The training loss curves of the generator (blue) and evaluator (red). (e) The curves of evaluator loss components including the real (red) and fake (blue) scores. (f) The MSE between Lab predicted by generator and ground truth (red), and generator’s fake score (blue).

Figure 4:
The distribution comparison between ground truth and prediction. The thickness histograms of (a–c) the testing set and (d–f) predicted by the generator.

Figure 5:
The tendencies of solution group number and ΔE as z sampling number varies.
(a and b) The solution group number histograms when each Lab combines 100 (a) and 1000 z (b). (c) The curve of average testing solution group number against z number, the circle and triangle markers refer to the solution group numbers when each Lab assigned with 1000 and 2100 z, respectively. (d and e) The testing ΔE histograms when each Lab is assigned with 1 (d) and 1000 (e) z, respectively. (f) The curve of average testing ΔE against z number, in which the insert is the enlarge of yellow shading region, the circle and triangle markers refer to the ΔE while each Lab assigned with the z number of 15 and 400.

Figure 6:
The analysis of sRGB color filter design results.
(a–c) The MSE curves of the colors with sRGB values of (a) (0.5, 0, 0 red), (b) (0, 0.5, 0 green), and (c) (0, 0, 0.5 blue) when the SiO2 thickness (d 2) was swept from 0 to 1000 nm and Ag thicknesses (d 1 and d 3) were fixed at 30 nm. The DBSCAN clustered predicted d 2 histograms for the (d) red, (e) green and (f) blue colors. The dark-colored bar indicates the lower resonant order, and the light-colored bar means the higher order.

Figure 7:
The experimental results of fabricated sRGB color filters.
(a–c) The cross-sectional SEM images of the fabricated color filters with all the scale bars of 100 nm. (d–f) The measured spectra (solid line) and corresponding theoretical ones (dash line). (g–i) The color reconstructions, wherein TGT. is the target color; DSG. is the theoretical color of the designed color filter; EXPT. SPT. is the theoretical color of the measured spectrum and EXPT. PHT. is the photograph of the sample taken by the camera.
