Creating longer linspace array from 2 linspace arrays

Hello, This is my first time asking a question on here! I'm struggling to find anyone trying to do what I'm doing so hoping someone can help.

Bit of background: I have some surfaces for a project and I want to create custom colormaps for them. That was fine when I was doing a gradient between 2 colours however now to fit with a colour scheme I'm wanting a gradient of 4 colours. Below is what I've been using for 2 colours

len=100;

LightB =[18, 198, 239]/255;
DarkB =[10, 42, 211]/255;

colour_blues = [linspace(DarkB(1),LightB(1),len)',linspace(DarkB(2),LightB(2),len)',linspace(DarkB(3),LightB(3),len)'];

colormap(colour_blues)

Works great but now I'm wanting to use the following colours in that order

Peach = [255, 102, 99]/255;
Green = [147, 229, 171]/255;
LightB =[18, 198, 239]/255;
DarkB =[10, 42, 211]/255;

My current thought process is to create 3 of these linspace arrays (for each RGB element) as the blends between the individual colours and then stick them together one on top of each other, hence the title. Here is where I'm at:

len=99;
Peach = [255, 102, 99]/255;
Green = [147, 229, 171]/255;
LightB =[18, 198, 239]/255;
DarkB =[10, 42, 211]/255;

e1blend1=linspace(Peach(1),Green(1),len/3)';
e1blend2=linspace(Green(1),LightB(1),len/3)';
e1blend2=linspace(LightB(1),DarkB(1),len/3)';
% etc ...

So basically I want to create a new array where the elements of e1bend1 are elements 1-33, e1bend2 are elements 34-67 and so on.

Can anyone let me know if there is a way of doing this? or better yet an easier solution to create a 4 colour gradient for a colormap! TIA

eblend=[e1blend1;e1blend2;e1blend3];

Thank you! Seems so obvious now :)
