Building a bitmap from random color data?

Hello, I have been using autoit for a while now, and I have a code that generates some random hexadecimal data. I was wondering if it would be possible to build a bitmap of this? Like maybe make each pixel a different color based on the data. Like below?

color1->color2->color3->color4->color5
colorN->colorN->colorN->colorN->colorN
colorN->colorN->colorN->colorN->colorN
colorN->colorN->colorN->colorN->colorN
colorN->colorN->colorN->colorN->colorN
