Piping results through some other program usually cause origin program to not
install color codes.
For a more specific solutions, look into each program's documentation.

See
http://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h2-Operating-System-Controls
Normal ANSI escapes start with CSI 0x9b or \e[, these start with OSC 0x9d or \e],
and end with ST 0x9c or \e\\, or BEL ctrl-G, 0x07 or \a.
See Ps = 4 ; c ; spec â Change colour c to colour spec, a standard xterm RGB
colour word or hex code; the ; c ; spec sequences may be repeated as many times
as required before the ST, e.g. for up to 256 colours.
See also Ps = 10 default foreground colour and 11 default background colour
if you need to temporarily invert the default background and foreground colours,
e.g to display curl wttr.in[/CityName] in a normally white window background:
#!/bin/bash
# wttr.sh - ANSI colour text weather forecast for IP address or city
echo -ne '\e]10;white\e\\'
echo -ne '\e]11;black\e\\'
curl wttr.in
sleep 5
echo -ne '\e]10;black\e\\'
echo -ne '\e]11;white\e\\'
as the colours just don't work without the black background.
N.B. The OSC sequences do not appear to be supported by man or less.

Set Mintty's yellow colour to be something legible against your chosen
background colour.
(Come to think of it, I should rebase my old GUI colour selection patch.
I probably should update Mintty anyway. But all that would require
effort.)
P.S. Sorry about mailing you directly David.

I've managed to resolve this. I turned off color output in the cqlsh
config file. It doesn't provide a way that I can see to configure the
colors that are used, and black works perfectly fine for me.

Mintty has meanwhile support for colour schemes ("themes") and
cooperates with the Color Scheme Designer for that purpose, which I
consider an excellent solution and easier to use than individual colour
configuration.
