Draw the national flag of France

Pure Bash (on OSX), 84

The default OSX terminal supports full colour emojis. Not sure if this counts as text or graphical output.

printf -vs %26s
for i in {1..26}
do echo ${s// /}${s// /⚪️}${s// /}
done

Output looks like:

---

Alternatively:

Bash with OSX utilities, 56

yes `dc -e3do26^d1-dn2/*p|tr 201 ⚪️`|sed 26q

The dc expression:

• calculates 3^26-1 and prints it in ternary 22222222222222222222222222
• divides this by 2, then multiplies by 3^26. Output in ternary this is 1111111111111111111111111100000000000000000000000000

tr then translates the 210 characters to ⚪️. yes outputs this line indefinitely. sed 26q halts output at 26 lines.

s="[3%smF";print(s%4*26+s%7*26+s%1*26+"\n")*30

Contains unprintables - here's a hexdump (reversible with xxd -r):

00000000: 733d 221b 5b33 2573 3b31 6d46 223b 7072  s=".[3%s;1mF";pr

00000020: 362b 7325 312a 3236 2b22 5c6e 2229 2a33  6+s%1*26+"\n")*3
00000030: 30                                       0

Uses ANSI escape codes to print colored characters to STDOUT - I chose "F" for France. No online link because ideone doesn't support ANSI escape codes in output.

Thanks to Dennis and xnor for some great tips.
