色盲(Color blindness),也称为色觉缺陷(color vision deficiency),是无法看到颜色区分颜色。色盲(Color)影响着世界各地的大量个体,大约 8% 的高加索男性和 0.5% 的女性存在某些形式的色盲问题。这意味着 20 位用户中的 1 位可能无法看到一个完整的网站。对于这些色盲的观众来说,文字和图像可能会模糊不清,无法辨认。幸运的是,有许多针对使用Windows(Windows)计算机的色盲人士的辅助软件产品。其中五个已在下面讨论。
(Computer Software)色盲计算机(Color Blindness)软件
1] 解决
(Visolve)Ryobi Systems Solutions的(Ryobi Systems Solutions)Visolve是一款软件,它使用滤镜通过使颜色更亮和更暗或增加饱和度来更好地区分颜色。除了颜色转换,Visolve还具有颜色过滤和阴影功能。通过这样做,它增强了数字内容的可访问性和可用性。 Visolve适用于Windows、Mac OS X和 iPhone。我可以从这里下载。(here.)
2] 色盲扩展
ColorBlindExt是一个Firefox插件,通过根据用户患有的色盲类型处理页面上的图像和文本,帮助色盲人士浏览网页。安装软件后,鼓励用户进行色盲测试,以帮助识别用户患有的色盲类型。过滤器根据测试结果设置,但也可以随时更改。
3]眼睛飞行员
EyePilot 是另一种带有几种不同类型过滤器的软件。除了通常的闪烁和名称过滤器,它们分别闪烁选定的颜色并显示鼠标指向的颜色的名称,eyePilot 有一个灰色过滤器。灰色过滤器通过将除用户选择的一种颜色之外的所有颜色变灰来帮助更好地识别颜色。除此之外,eyePilot 的色调过滤器可以改变颜色的饱和度,从而增加它们之间的对比度。它可以从这里(here)下载。
4]达尔塔普
Daltap是Glenn Heylen的一款辅助软件,具有许多有用的功能。它的命名功能在光标尖端给出颜色的名称,同时还允许用户放大或放大鼠标周围的区域。Daltap的一个非常流行和有用的功能是闪烁功能,它显示所选颜色在屏幕上的位置。它可以从这里(here)下载。
5]什么颜色
WhatColor是一款免费软件,可让用户通过选择像素来识别颜色。该程序放大光标周围的区域,用户可以从中选择一些像素进行识别。然后程序将告诉用户所选像素的颜色,并为其提供RGB值。然而,WhatColor受到一些限制。(WhatColor)
鉴于它用于识别和通知用户颜色,如果色盲用户需要参考文档中的颜色,它会派上用场;或者如果另一个文档或页面提到了可能不清楚的特定颜色。此外,它只能与Windows 7、8(Windows 7)和 10 一起使用。可以从这里(here)下载。

5 Free Computer Software for Color Blindness
Color blindness, also known as color vision deficiency, is the inability to see color distinguish colors. Color blindness affects a large number of individuals across the world, with approximately 8% of all Caucasian males and 0.5% of females experiencing problems with some forms of color deficiency. This means that 1 of 20 users may not be able to see a website in its full beauty. For these viewers with color blindness, the text and images may be fuzzy and unrecognizable. Fortunately, there are numerous assistive software products for color blind people using a Windows computer. Five of them have been discussed below.
Computer Software for Color Blindness
1] Visolve
Visolve by Ryobi Systems Solutions is a software that uses filters to allow better differentiation between colors by making colors lighter and darker or increasing the saturation. In addition to color conversion, Visolve also has color filtering and hatching capabilities. By doing so, it enhances the accessibility and usability of digital content. Visolve is available for Windows, Mac OS X, and iPhones. I can be downloaded from here.
2] ColorBlindExt
ColorBlindExt is a Firefox add-on that helps color blind people while browsing the web, by processing images and text on the page according to the type of color blindness the user suffers from. After installation of the software, users are encouraged to take the color blindness test that helps identify the type of color blindness the user suffers from. The filter gets set according to the test result but can also be changed anytime.
3] eyePilot
EyePilot is another software that comes with several different types of filters. Along with the usual flashing and name filters that flash a selected color and show the name of the color that the mouse points at respectively, eyePilot has a gray filter. The gray filter helps in better identification of colors by graying out all colors except the one color chosen by the user. In addition to this, eyePilot’s hue filter can change the saturation of colors, thus increasing the contrast between them. It can be downloaded from here.
4] Daltap
Daltap is an assistive software by Glenn Heylen that comes with many useful features. Its naming feature gives the name of the color at the tip of the cursor while also enabling the user to enlarge or zoom in the area around the mouse. An extremely popular and useful feature of Daltap is the flashing feature which shows where a selected color is on the screen. It can be downloaded from here.
5] WhatColor
WhatColor is a freeware that enables users to identify colors by selecting pixels. The program magnifies an area around the cursor from which the user can select some pixels to identify. The program will then tell the user the color of the selected pixel is, along with providing an RGB value for it. WhatColor, however, suffers from some limitations.
Given its use in identifying and notifying the color to the user, it can come in handy if color-blind users need to refer to colors in a document; or if another document or page refers to specific colors that might otherwise not be clear. Further, it can only be used with Windows 7, 8 and 10. It can be downloaded from here.
