Something like this would work, for the bars:
data = randi([3 6],120,1);
colors = [ ...
61 99 89; ...
66 145 128; ...
135 189 166; ...
191 163 97]/255;
barh((1:120)/4,data, ...
'BarWidth',1, ...
'FaceColor','flat', ...
'CData',colors(data-2,:), ...
'EdgeColor','none')
set(gca(),'YDir','reverse','XLim',[0 18])
Here, since each element of data is an integer between 3 and 6 (inclusive), and since each bar is colored according to the value of the corresponding element in data, I use data to index into the set of colors colors. Specifically, when data is 3, the corresponding color is the 1st row of colors, when data is 4, the color is the 2nd row of colors, and so on, so colors(data-2,:) is the colors of all the bars.
For the text labels, I assume that a data value of 2 corresponds to 'Clay', 3 is 'Clay & silty clay', and so on, so that determining the label for each data point can be done with the same indexing as for the colors. It's not clear how to determine which bars get text labels, so here I'm making a label for every 6th bar. I imagine the final result would require some fine-tuning by hand to choose which bars get labels.
labels = { ...
'Clay' ...
'Clay & silty clay' ...
'Silty sand & sandy silt' ...
'Sand & silty sand'};
text(9*ones(1,20),(1:6:120)/4,labels(data(1:6:end)-2))
