PIGMENT
Lemon yellow:
The pigment known commonly as "lemon yellow" could consist of barium chromate, strontium chromate, or a mixture of lead chromate with lead sulphate. The preparation was described by Vauquelin in 1809, but some years seem to have passed before it was produced commercially. During the nineteenth century, it was often mixed with strontium chromate, and the name "lemon yellow" was liable to be used for barium chromate, strontium chromate and a mixture of the two. It´s a stable yellow with low hiding power.
Watercolor: watercolor paints are renowned for their ability to capture the fleeting essence of light as it fluctuates throughout the day earmarking the passage of time.
