Are you looking for a simple and boxy/blocky resource pack that looks like this: ?

Then this is not your pack. You can click the ‘Back’ button of your
browser and try to find another pack. But if you’re looking for an
alternative for those packs, and you think that simple doesn’t mean
bucket fill, that simple packs can be done right, you should stay here
and scroll down for the screenshots.

About:
This pack was born from the idea of another great 16x texture pack,
SineCraft. That simple pack used a pattern of squares and four different
colors to make textures for all the blocks. But most of the blocks
didn’t have borders, so, as you can see in the image above, blocks are
connected, creating a huge mosaic, and not separated boxes or blocks.

I liked that idea; it was original. But I didn’t like the feeling and
the atmosphere of the pack. The colors were rather dull and had very low
saturation. So I decided to start changing those aspects of the pack I
didn’t like. I like colorful Minecraft, so I saturated all the colors. I
changed or improved lots of textures taking ideas, concepts or colors
from other packs or from my own mind, and finally changed the pattern,
keeping the 16x resolution.

Décor 2 is the next step: the pattern has shading and much more detail
now, and there are 11 colors in most textures. Not bad for a simplistic
pack. I’ve also revised all the textures and added or changed things
here and there.

My favorite items are vanilla ones, but they’re too low-res. So I
decided to add Faithful 32x items, but I’ve been heavily editing them
with the time, making them a great alternative to vanilla items without
losing Minecraft style.

Mobs are Tronic ones, some have been edited, but they’re pretty much the same ones.

So this pack is 16x blocks, 32x items and 64x mobs. I think those are
the best resolutions for Minecraft. There are also tons of MC Patcher
features, including CTM, Custom Sky and Custom Colors.

I’ve already been some years working hard on this pack for the best Minecraft experience.
I hope you like it!

Features:

Lots of MC Patcher/OptiFine textures, such as: custom colormaps, custom sky, custom lightmaps, CTM, random mobs, color.properties (lots of custom colors!), CIT...
Some animated textures.
Some optional add-ons, so that Décor 2 can offer a more customised experience to users.
The Nether has a red lightmap.
The End has an outer space look.
Changes between biome colors are more drastic.
A simple yet detailed resource pack.
A more colorful Minecraft!

Feel free to contact me with doubts, suggestions, tips, bug reports or critics.
You are free to make any video showcase or to use this pack in your videos, as long as you provide a link to this thread.
I’m constantly improving this pack: my aim is to offer to the best Minecraft experience.
I try to update Décor 2 for snapshots. However, I don’t always have time for that.
My custom sky does have clouds, so you can disable vanilla ones if you want.
Some blocks have borders. However, most of the blocks are border-free. The only blocks that have borders are crystal-like blocks, like diamond, glowstone or gold blocks.
The box above was made by me (?).
There are autumn colormaps in the pack, if you want to use them, replace them with the original ones.
I recommend MCPatcher over OptiFine, since it seems that OptiFine CTM is more limited.
Yes, if you name an Iron Sword 'Pan', it will become a pan (?).
If you name a Diamond Sword 'Excalibur', it will have a different texture.
