+gotest comes with many colors! Configure the color of the output by setting the following environment variables:
+
+- `GOTEST_FAIL`
+- `GOTEST_PASS`
+- `GOTEST_SKIP`
+
+Alternatively you can use a single environment supporting a list of colors, in the order: fail, pass, and skip.
 
 ```
 $ GOTEST_PALETTE="magenta,white"
 ```
 
 The output will have magenta for failed cases, white for success.
 Available colors: black, hiblack, red, hired, green, higreen, yellow, hiyellow, blue, hiblue, magenta, himagenta, cyan, hicyan, white, hiwhite.
+
+Do note that the individually set environment variables take precedence over the palette variable
+
+For the setting:
+
+```
+$ GOTEST_PASS="hiblue" GOTEST_PALETTE="magenta,white"
+```
+
+The output will have magenta for failed cases, hiblue for success.
