Opaque and transparent pigments in oil painting

I'm going to use a basic palette of cool and warm primaries and in each of the colours an opaque and transparent version. From this palette I'm going to start with cadmium yellow, which you can see is a really nice strong opaque warm yellow. And pulling down on the transparent yellow you can see that it allows the black to show through, which would make it really good for glazing. With the cadmium red, unlike the cadmium yellow, it’s completely opaque. Whereas the permanent rose you can see it allows the dark and the light to show through and again would be a really good colour to use when glazing. The cerulean blue like the cadmiums has a really strong opacity, a really nice heavy, solid colour that doesn't allow the light or the darks to shine through. Whereas the ultramarine blue allows the light and the dark to show through making it an excellent colour for glazing. I hope this insight will give you a greater understanding of your palettes and acquainting yourself with opaque and transparent pigments.
