Robert Oster Evening Sapphire Ink Bottle

Robert Oster Evening Sapphire Ink

Robert Oster has continued to produce new and exciting colors for their wide array of Australian’s world of color. This fountain pen ink has the trademark,“A Drink for your Pen,” which is prolific in their production of ink colors. Even though they are continually producing many new ink colors, each one is still interesting and unique. Robert Oster Evening Sapphire ink is a beautiful shade of blue, but the name is somewhat misleading. The blue is not a bright deep color as one would expect from a sapphire stone, but more of a muted blue with grey undertones. Evening Sapphire ink is the perfect name as the color defines an evening blue at sunset. Robert Oster Evening Sapphire ink also has a slight hint of light pink sheen.

We found that Robert Oster Evening Sapphire ink produces some nice shading characteristics with the right pen nib and hand. There are soft light blue-grey colors to a darker blue-black color. To top it all off, during the wettest lines you may see a slight pink sheen. Robert Oster Evening Sapphire ink is quite a remarkable color.

Nice blue, but I wouldn’t have named it sapphire. Too dull. Sapphires are brighter.

Like the blue shade, but I also think Sapphire isn’t a proper name given its darkness.
