I have no idea how to implement color mid-print but color is achieved by these commands

EDIT: Remember that you have to do the gpu getting at the first lines of the program(before anything else happens in the code)

--Get GPU
local c = require("component")
local gpu = c.gpu
--Set Foreground(text color), or Background(Background color)
--Background color only changes for the places BEHIND THE TEXT PRINTED AFTER THIS
gpu.setForeground(0x444444) - set text to gray
gpu.setBackground(0x33DBFF) - set background to light blue

This was my test result by changing the background color then writing the text, changing the cursor position, and repeating. I don't know exactly how you would go about this over the whole screen, but i hope this helps

local gpu = require("component").gpu
local term = require("term")
--cursor is already set a (1,1), no need to change anything if you don't want to
gpu.setBackground(0x003d99) -- example dark blue
term.write("Insert your stuff here, this is basically like the print function except no auto indenting!") -- color should be different BEHIND the text here
term.setCursor(1,3) -- Moves cursor down a bit
gpu.setBackground(0x005ce6) -- Normal Blue
term.write("yada yada") --only should be color behind the text
term.setCursor(1,4) -- this is what made mine connect for some reason
gpu.setBackground(0x66a3ff) --Lighter blue
term.write("You get the idea") -- only color behind the text

Hope this helps!

Well, last i checked ComputerCraft does essentially the same thing without hexadecimal if i recall correctly, but the way i would go about it is on the next line, change it back to white with

gpu.setForeground(0xFFFFFF)

so your finished code would be

local term = require("term")
local component = require("component")
local gpu = component.gpu
term.clear()
print(gpu.setForeground(0x2E86C1) .. "Test")
gpu.setForeground(0xFFFFFF)

I've been working on this library to automatically change decimal to hexadecimal, but i've been running into a few problems. The first one being that for some reason when i try to load the library, it returns;

home/test; 1; module 'hex' not found

    no field package.preload['hex']

    no field package.delayed['hex']

/lib/hex.lua; 3; <name> expected near '='

Here's the code:

hex = {}

local function = hex.toHex(input)
	local a = input/16
	local b = a/16
	local c = b/16
	local d = c/16
	local e = d/16
	local g = input%16
	local h = a%16
	local i = b%16
	local j = c%16
	local k = d%16
	local l = e%16
	if g,h,i,j,k,l < 9 then
		if g = 10 then
			g = "a"
		end
		if g = 11 then
			g = "b"
		end
		if g = 12 then
			g = "c"
		end
		if g = 13 then
			g = "d"
		end
		if g = 14 then
			g = "e"
		end
		if g = 15 then
			g = "f"
		end
		if h = 10 then
			h = "a"
		end
		if h = 11 then
			h = "b"
		end
		if h = 12 then
			h = "c"
		end
		if h = 13 then
			h = "d"
		end
		if h = 14 then
			h = "e"
		end
		if h = 15 then
			h = "f"
		end
		if i = 10 then
			i = "a"
		end
		if i = 11 then
			i = "b"
		end
		if i = 12 then
			i = "c"
		end
		if i = 13 then
			i = "d"
		end
		if i = 14 then
			i = "e"
		end
		if i = 15 then
			i = "f"
		end
		if j = 10 then
			j = "a"
		end
		if j = 11 then
			j = "b"
		end
		if j = 12 then
			j = "c"
		end
		if j = 13 then
			j = "d"
		end
		if j = 14 then
			j = "e"
		end
		if j = 15 then
			j = "f"
		end
		if k = 10 then
			k = "a"
		end
		if k = 11 then
			k = "b"
		end
		if k = 12 then
			k = "c"
		end
		if k = 13 then
			k = "d"
		end
		if k = 14 then
			k = "e"
		end
		if k = 15 then
			k = "f"
		end
		if l = 10 then
			l = "a"
		end
		if l = 11 then
			l = "b"
		end
		if l = 12 then
			l = "c"
		end
		if l = 13 then
			l = "d"
		end
		if l = 14 then
			l = "e"
		end
		if l = 15 then
			l = "f"
		end
		local hexnum = tonumber(l..k..j..i..h..g)
		return hexnum
	end
	return hex

Sorry it's so long!
