Use the colors that were given in the styleguide.md found in the zip folder you downloaded.

For the color of the image, there is no need for a linear gradient, give .imageoverlayer a background-color of soft violet, background-blend-mode of multiply and opacity: 0.8.

.imagerOverlayer{
background-image: url();
