Water – Cobalt Blue


This is a blue water material for Maxwell Render and for Realflow. This color is useful for applying to water elements when you need a tinge (a small trace) of color in the water.

The zip file contains a folder with several material files, all with this same color, but varying in terms of light attenuation length. The materials with shorter attentuation lengths are suitable for relatively small water objects, while the files with longer lengths are suitable for larger objects.

Maxwell Render users will need only a single of these material files, and may adjust its properties as needed to suit their scene needs.

Realflow users will find a complete installation and use guide within the zip folder.


There are four cases in which you might want a trace of the Water – Cobalt Blue color in the waters of your Maxwell Render or Realflow scene.

First, your scene might use a light or sun source positioned almost directly overhead. In this case, the default “pure water” material that ships with Next Limit products may display with great difficulty. You may be able to see the edges of the water, where light distortion is greatest, but your water will not be well-defined in your image.

Second, for close-up views, you might want small traces of color to enhance flowing waters when seen against certain objects in a scene, such as the bronze of metal fixtures in a fountain.

Third, you may want a large body of water to have a one or more specific shades of color to contrast with other elements of your scene. For example, you want a waterfall to have one or more slight green colors.

And fourth, you may be using an HDRI photo for background, and you want the water to seemingly pick up the highlights of the background image, such as the red-gold elements of a sunset.

Here are some technical details about the water materials in this package —

The color of the Maxwell Render Material “Water – Cobalt Blue” is based on the European RAL 5013 color specification, using the HSV value 218, 166, 83 as used by Next Limit for this color. Different sources seem to provide significantly different sets of HSV values for the standard RAL colors. In general, I use the www.encycolorpedia.com conversion guide when I want to find the HSV specifications for a given RAL color. As nearly as I can determine, the colors created using the Next Limit HSV values for the RAL Blue series appear to be about the same as the colors made using the Encycolorpedia HSV values, but the Next Limit values tend to be a little brighter. Therefore, I used the Next Limit HSV values.

These materials also all have a forced dispersion value so that the color appears as evenly in a large body seen at a distance as in a small body.
