To better understand how to implement CVD themes in the Bloomberg Terminal, we first needed to evaluate the user experience of our clients with CVD. Because of this, we needed to take a researched approach to make our product more inclusive. Apple iOS also includes a small set of preset colors that can be selected for specific CVD types, but this has disadvantages in that it changes specific colors that are crucial in the financial industry. These settings cater to a more general approach in an attempt to cover multiple types of vision deficiencies. Operating systems, such as Microsoft Windows or Apple macOS, have enhanced contrast or increased text legibility support to aid in accessibility. This could potentially have large financial repercussions, when using our system to make a decision to trade millions of dollars of securities could be affected by these important visual indicators. While there still are individual differences between different people, itвЂ™s clear that these reds and greens are difficult for these users to distinguish.

Using this CVD simulator (as shown in Image 4), we can see what an example from the Terminal looks like from the perspective of a user with Deuteranopia.

Software programs can simulate the approximate colors that a person with CVD might see. The Deuteranopia simulation exposes that the red and green colors appear very similar in hue, and makes it challenging to quickly parse the two different color indicators.

Red colors are associated with вЂњdownвЂќ market status and green colors are associated with вЂњupвЂќ market status.

For example, green generally indicates an вЂњupвЂќ market status, while red generally indicates a вЂњdownвЂќ market status. In the financial industry, red and green are key visual indicators, because they express positive and negative semantic meanings in Western conventions (Image 3). However, even by conservative estimates, 20,000 or more of our Terminal users could have the most common form of CVD, Red-Green. There are varying prevalence rates of CVD across ethnicities (due to its genetic component) and genders (with CVD predominantly affecting males). Clockwise from Top Left: Normal Vision, Red-Green Confusion, Monochromacy (canвЂ™t perceive color at all), and Blue-Yellow Confusion. Image 2: A comparison of the same image simulating Normal Vision and the three main types of Color Vision Deficiency. Imagine not knowing if your clothing matches, accidentally eating unripened (green) bananas, or being unable to tell one sporting teamвЂ™s jersey from another when watching a game on TV. This deficiency certainly affects peopleвЂ™s everyday experiences. The most common form of CVD affects the red and green wavelengths of the color spectrum. These color vision deficiencies can take many forms (Image 2). The scientific terms are dichromacy (a type of color deficiency where one cone cell is completely absent вЂ“ for example, if the green cone cell is absent, it is called Deuteranopia) and anomalous trichromacy (a type of color deficiency where one cone cell has a reduced sensitivity to certain wavelengths of light вЂ“ for example, having reduced sensitivity to green light is called Deuteranomaly).
