This dataset contains:
The raw data of Figure 1, 2, 3 and 5.
The dataset training and test neural network.

The figures are as follows:

Fig. 1. (a) The schematic of the proposed five-layer structure. (b) The reflective spectra of the structure with the thickness of D (100, 5, 100, 100) nm at 30°C (cyan curve) and 85°C (red curve), in which the inserts are the corresponding colors. (c, d) The CIE 1931-xy chromaticity diagrams of the dataset at 30°C (c) and 85°C (d).

Fig. 2. (a) The data flow and the cGAN architecture in this work. (b) The loss curves of discriminator (black curve) and generator (red curve). (c) The components of discriminator loss, where the black curve is the fake score and the red curve is the real score. (d) The components of generator loss, where the black curve is the fake score, the red curve is the MSE which is computed between the input Lab and predicted Lab in Fig. 2(a).

Fig. 3. (a, b) The testing ΔE histograms when each Lab is assigned with 1 z (a) and 1,000 z (b), respectively. (c) The testing average ΔE as the function of the number of z, in which the insert is the enlargement of the yellow shade region. (d) Eight cGAN inverse design examples, the target colors with 30°C are outlined by a blue dash frame (left), and the target colors with 85°C are outlined by a red dash frame (right).

Fig. 5. The spectra of (a) solution 1 and (b) solution 2, where the inserts are the corresponding colors of the spectra. The reconstructed campus photo (c) at 30°C and (d) at 85°C.
